Oral health is much more than having a bright smile. A healthy mouth helps us eat, speak, communicate and live comfortably. Problems affecting the teeth, gums and other tissues of the mouth can cause pain, difficulty eating, loss of teeth and can affect overall wellbeing.
Many common oral diseases, including tooth decay and gum disease, are largely preventable through good daily oral hygiene, a healthy diet, avoidance of tobacco and regular professional dental care. Oral health is important at every stage of life—from infancy and childhood to old age.
Take care of your mouth. Protect your health. Visit your dentist regularly.
Good oral health begins even before the first tooth appears.
Parents should begin cleaning an infant’s mouth and gums gently and establish healthy feeding and oral-hygiene habits early. Once teeth erupt, brushing with an age-appropriate amount of fluoride toothpaste becomes important.
Children’s baby teeth are important for eating, speaking and maintaining space for permanent teeth. Tooth decay in baby teeth can cause pain, infection and difficulty eating.
Parents should remember:
Begin oral care from infancy.
Avoid frequent sugary foods and drinks.
Never put a baby to sleep with a bottle containing milk or sugary drinks.
Start brushing as soon as the first tooth appears.
Supervise children’s brushing.
Encourage healthy food and water.
Take children for regular dental examinations.
A healthy childhood smile is an investment for life.
Life Stage
Adolescents
Healthy Teeth During the Growing Years
Adolescence brings major changes in the mouth, diet and lifestyle. Increased consumption of sugary foods and drinks, orthodontic treatment, sports activities, tobacco use and poor oral hygiene can affect oral health.
Teenagers should pay particular attention to:
Tooth decay
Gum inflammation
Orthodontic problems
Wisdom teeth
Dental injuries during sports
Tobacco and vaping
Sugary drinks and snacks
Those wearing braces require particularly careful cleaning around brackets and wires.
Healthy habits during adolescence can prevent many dental problems later in life.
Regular brushing with fluoride toothpaste, cleaning between the teeth, limiting free sugars, avoiding tobacco and attending regular dental examinations can significantly reduce the risk of oral disease.
Dental problems should not be ignored simply because they are painless. Many conditions, particularly gum disease, may progress with few symptoms in the early stages.
Don’t wait for pain. Prevention is better than treatment.
Life Stage
Women & Pregnancy
Oral Health During Pregnancy
Pregnancy causes hormonal and physical changes that can affect the gums and other aspects of oral health. Some women may experience swollen or bleeding gums, nausea, changes in eating habits or increased susceptibility to dental problems.
Good oral hygiene and appropriate professional dental care remain important during pregnancy.
Remember:
Continue regular brushing.
Clean between the teeth.
Maintain a balanced diet.
Limit sugary snacks and drinks.
Inform your dentist that you are pregnant.
Do not postpone necessary dental care without discussing it with your dentist.
A healthy mother supports a healthy family—including healthy oral habits for the next generation.
Life Stage
Senior Citizens
Healthy Teeth and Gums at Every Age
Age itself does not cause tooth loss. Teeth can remain healthy throughout life when oral diseases are prevented and treated appropriately.
Older adults may be more susceptible to:
Gum disease
Root decay
Dry mouth
Tooth wear
Tooth loss
Denture-related problems
Oral infections
Some medicines and medical conditions can contribute to dry mouth and other oral problems. Regular dental examinations, good oral hygiene, proper denture care and adequate nutrition are important for maintaining oral health.
Healthy teeth and a comfortable mouth contribute to better nutrition, communication and quality of life.
Life Stage
Special Care
Oral Health for People Who Need Additional Support
People with physical, intellectual, developmental or medical conditions may require additional support to maintain oral health.
Give importance to:
Daily oral hygiene
Monitoring changes in the mouth
Managing diet
Ensuring regular dental visits
Helping with dentures or oral appliances
Dental care should be individualised according to the person’s needs and medical condition.
Every person deserves access to compassionate and appropriate oral healthcare.
COMMON ORAL PROBLEMS
Know the common problems, recognise the signs and take early action.
Tooth Decay
Dental Caries
Tooth decay occurs when acids produced by bacteria in dental plaque gradually damage the tooth.
Frequent consumption of foods and drinks containing free sugars, inadequate plaque removal and insufficient fluoride exposure increase the risk of decay. Untreated decay can progress to pain, infection and tooth loss.
Prevention
Brush twice daily with fluoride toothpaste.
Clean between teeth.
Limit frequent sugary foods and drinks.
Choose water as the main drink.
Visit your dentist regularly.
Early decay can often be managed more conservatively than advanced disease.
Gum Disease
Healthy Gums Support Healthy Teeth
Gum disease begins with inflammation caused by plaque around the teeth.
Early gum disease may cause:
Red or swollen gums
Bleeding during brushing
Bad breath
If gum disease progresses, the tissues and bone supporting the teeth can become damaged, potentially causing loose teeth and tooth loss.
Prevention
Good oral hygiene, professional dental care and avoidance of tobacco are important.
Bleeding gums should not simply be considered “normal.”
Bleeding Gums
Why Are My Gums Bleeding?
Bleeding gums are commonly associated with gum inflammation, usually caused by plaque accumulation. They may also occur because of other local or systemic factors.
Do not stop brushing because your gums bleed. Gentle but thorough cleaning is important.
If bleeding persists, is frequent or is associated with swelling, pain, bad breath or loose teeth, consult a dentist.
Healthy gums generally should not bleed regularly during routine brushing.
Tooth Sensitivity
Why Do My Teeth Hurt When I Have Something Cold or Hot?
Tooth sensitivity may occur when the protective enamel or gum tissue is lost and the underlying dentine becomes exposed.
It may be associated with:
Gum recession
Tooth wear
Erosion
Abrasion
Tooth decay
Cracked teeth
Persistent or severe sensitivity should be evaluated by a dentist because the underlying cause needs to be identified.
Don’t simply treat sensitivity with toothpaste without finding out why it is happening.
Bad Breath
Bad Breath – More Than a Social Concern
Bad breath, or halitosis, can arise from the mouth or from other causes.
Common oral causes include:
Poor oral hygiene
Tongue coating
Gum disease
Food debris
Dry mouth
Certain dental conditions
Regular brushing, cleaning between the teeth and gently cleaning the tongue can help. Persistent bad breath deserves professional assessment.
Fresh breath begins with a healthy mouth.
Mouth Ulcers
Most Are Harmless – But Persistent Ulcers Need Attention
Mouth ulcers are common and may result from minor injury, irritation, infections or other causes. Many heal on their own.
However, an ulcer that does not heal, repeatedly returns, becomes larger, bleeds or is associated with other changes in the mouth should be examined by a dentist or doctor.
Particular attention is required in people who use tobacco, areca nut or alcohol.
If a mouth lesion persists, don’t ignore it.
Tooth Wear
When Teeth Gradually Lose Their Surface
Tooth wear is the gradual loss of tooth structure.
It may occur because of:
Erosion from acids
Abrasion
Attrition
Grinding or clenching
Dietary habits
Excessive consumption of acidic foods and drinks and aggressive brushing may contribute. Early assessment can help identify the cause and prevent further damage.
Dry Mouth
When Your Mouth Doesn’t Produce Enough Saliva
Dry mouth, or xerostomia, can cause discomfort and may increase the risk of tooth decay, difficulty swallowing, speaking problems and oral infections.
It may be associated with medications, medical conditions, dehydration or other factors.
If you frequently experience dry mouth, discuss it with your dentist or doctor.
Do not stop prescribed medicines without medical advice.
Missing Teeth
Replacing Missing Teeth – Why It Matters
Missing teeth can affect chewing, speech, appearance and quality of life. Tooth loss may result from decay, gum disease, trauma or other conditions.
Depending on individual circumstances, replacement options may include:
Bridges
Removable dentures
Dental implants
The most appropriate option depends on oral health, bone condition, general health, expectations and other factors. A dental examination is essential before choosing a replacement option.
Wisdom Teeth
Understanding Your Third Molars
Wisdom teeth are the last permanent teeth to develop and usually appear during late adolescence or early adulthood. They may erupt normally or become impacted because of lack of space.
Possible problems include:
Pain
Swelling
Infection
Gum inflammation
Food trapping
Damage to adjacent teeth
Not every wisdom tooth requires removal. Your dentist should assess the tooth and surrounding tissues before recommending treatment.
Dental Treatments – Understanding the Basics
Comprehensive evidence-based procedures to restore oral health and function.
Fillings
Restoring a Damaged Tooth
A filling is used to restore a tooth that has been damaged by decay or, in some situations, wear or minor fracture. The dentist removes the diseased or damaged tissue and restores the tooth with an appropriate filling material. Early treatment can help prevent decay from progressing deeper into the tooth.
Root Canal Treatment
Saving an Infected or Damaged Tooth
When the pulp—the living tissue inside a tooth—becomes irreversibly inflamed or infected, root canal treatment may be recommended to save the tooth. The procedure involves removing infected or damaged pulp tissue, cleaning and disinfecting the root canal system, filling it and restoring the tooth. Root canal treatment is intended to preserve the natural tooth when appropriate. A tooth that has undergone root canal treatment usually requires a suitable final restoration for long-term function.
Crowns & Bridges
Restoring Damaged or Missing Teeth
A crown is a restoration that covers and protects a damaged or weakened tooth. A bridge can replace one or more missing teeth by using neighbouring teeth or other appropriate support. The choice depends on the condition of the teeth, gums, bone, bite and overall oral health.
Dentures
Replacing Missing Teeth with Removable Prostheses
Dentures are removable appliances used to replace missing teeth and surrounding tissues. They may be Complete dentures or Partial dentures. Proper cleaning, maintenance and periodic dental review are important. A new denture may take time to become comfortable, and adjustments may sometimes be required. Consult your dentist if any complaints arise. Never ignore persistent pain or sores caused by a denture.
Dental Implants
A Modern Option for Replacing Missing Teeth
Dental implants are devices placed within the jawbone to support dental restorations such as crowns, bridges or dentures. Implant treatment requires careful assessment of: General health, Oral hygiene, Gum health, Bone availability, Smoking/tobacco habits, Bite and functional requirements. Implants are not suitable for everyone and require professional planning and maintenance. Successful implant treatment begins with appropriate diagnosis and long-term oral care.
Braces & Orthodontic Treatment
Straightening Teeth and Improving the Bite
Orthodontic treatment aims to correct problems involving the position of teeth and jaws. Treatment may: Improve alignment, Correct certain bite problems, Facilitate oral hygiene, Improve function and appearance. Treatment options may include fixed braces, removable appliances or clear aligner systems depending on individual needs. A proper assessment is necessary before deciding which treatment is appropriate.
Gum Treatment
Protecting the Foundation of Your Teeth
Gum treatment depends on the severity and type of gum disease. It may include: Professional cleaning, Improved home oral hygiene, Management of risk factors, Deep cleaning where indicated, Periodontal surgery in selected cases, Long-term maintenance. Tobacco cessation and control of relevant medical conditions are also important. Healthy gums are essential for keeping natural teeth healthy.
Oral Surgery
Surgical Care for Problems of the Mouth and Jaw
Oral surgery includes a range of procedures involving teeth, gums, jaws and other oral tissues. Examples include: Removal of impacted teeth, Complex tooth extraction, Treatment of oral infections, Biopsy of suspicious lesions, Management of certain cysts and other conditions, Treatment of TMJ Problems, Management of fracture jaws and skull bones, Cosmetic Facial Surgery, Management of Oral cancer. The type of procedure depends entirely on the individual diagnosis. Your dentist or oral and maxillofacial surgeon will explain the procedure, benefits, risks and alternatives before treatment.
Severe or persistent tooth pain can be caused by decay, inflammation of the dental pulp, infection, trauma or other conditions.
What you should do:
Arrange a dental examination as soon as possible.
Keep the area clean.
Follow appropriate pain-relief advice from a dentist.
Do not place aspirin or other chemicals directly on the gum.
If pain is accompanied by facial swelling, difficulty swallowing or breathing, seek urgent medical attention.
Facial Swelling
Dental Swelling Can Be an Emergency
Facial swelling may be caused by a dental infection and should not be ignored. A dental infection can sometimes spread beyond the tooth and surrounding tissues.
Seek urgent care if swelling is accompanied by:
Difficulty breathing
Difficulty swallowing
Difficulty opening the mouth
Rapidly increasing swelling
Fever or severe illness
Swelling involving the neck or floor of the mouth
Do not delay professional treatment or rely solely on home remedies!!!
Knocked-Out Tooth
A Knocked-Out Permanent Tooth Needs Urgent Attention
A completely displaced permanent tooth is a dental emergency.
If a permanent tooth is knocked out:
Handle the tooth by the crown, not the root.
If dirty, gently rinse it with clean water without scrubbing.
If possible and appropriate, gently place it back into its socket.
If that is not possible, keep it moist—preferably in an appropriate tooth-preservation solution or milk.
Seek emergency dental care immediately.
Do not allow the tooth to dry out.
Broken or Chipped Tooth
What to Do When a Tooth Breaks
A broken tooth may result from trauma, decay, biting hard objects or tooth wear.
If a piece of tooth has broken off:
Save the fragment if possible.
Rinse your mouth gently.
Avoid chewing on the affected side.
Arrange a dental examination promptly.
If there is severe pain, bleeding, swelling or significant trauma, seek urgent dental care.
Dental Trauma
Injuries to Teeth, Gums and Jaws
Dental trauma can occur during sports, falls, accidents or other injuries.
Injuries may involve:
Chipped teeth
Fractured teeth
Displacement of teeth
Knocked-out teeth
Gum injuries
Jaw injuries
Even when a tooth looks intact, internal damage may have occurred. Any significant dental injury should be assessed by a dentist as soon as possible.
Bleeding After Tooth Extraction
When Should You Be Concerned?
Some oozing after a tooth extraction is expected. Your dentist will usually provide instructions to help a blood clot form and remain in place.
If significant bleeding continues despite following the instructions given by your dentist, contact the dental clinic promptly. If bleeding is heavy, persistent or accompanied by dizziness or weakness, seek urgent medical care. Do not repeatedly disturb the extraction site or spit forcefully.
Oral Cancer
Early recognition, awareness, risk reduction and professional screening.
Warning Signs
Know the Warning Signs of Oral Cancer
Many changes in the mouth are harmless, but certain persistent changes need professional assessment.
Look out for:
A mouth ulcer that does not heal
Red or white patches
A persistent lump or thickened area
Unexplained bleeding
Persistent pain or discomfort
Difficulty chewing or swallowing
Difficulty moving the tongue or jaw
Persistent numbness
Unexplained loosening of a tooth
Persistent neck swelling
A persistent oral lesion should not be ignored. Early detection and appropriate professional evaluation are important in improving outcomes.
Risk Factors
Know What Increases the Risk
Important risk factors for oral and related cancers include:
Tobacco smoking
Smokeless tobacco
Areca nut/betel quid use
Alcohol consumption
Certain infections, including HPV for some cancers of the oropharynx
Increasing age
Other individual and environmental factors
Tobacco, alcohol and areca nut use are important preventable risk factors.
The best protection: Avoid tobacco and areca nut, limit alcohol, maintain good oral health and seek professional assessment of persistent oral changes.
Tobacco & Oral Cancer
Tobacco Harms the Mouth
Tobacco in any form can seriously affect oral health and is an important risk factor for oral cancer. Tobacco use is also associated with gum disease, tooth loss, delayed healing and other oral problems. Smokeless tobacco is not a safe alternative to smoking. If you use tobacco, quitting is one of the most important steps you can take for your oral and general health.
There is no safe form of tobacco.
When to Consult a Dentist
Don’t Wait Until It Hurts
You should seek professional dental advice if you have:
Persistent toothache
Bleeding gums
Facial or gum swelling
Persistent mouth ulcer
Red or white patch
Loose tooth
Difficulty chewing
Tooth sensitivity that persists
Persistent bad breath
Difficulty opening the mouth
A dental injury
Any unexplained change in the mouth
At least once in six months
People with tobacco or areca nut exposure should be particularly attentive to persistent oral changes.
When in doubt, get it checked.
Oral Cancer Screening
Early Detection Matters
A dental professional can examine the mouth, gums, tongue, cheeks, palate and other relevant areas for abnormalities during a routine clinical examination. A screening examination does not mean that every abnormality is cancer. Suspicious findings may require further evaluation, investigation or biopsy. There is no single home test that can reliably diagnose oral cancer.
IDA Kerala’s IDA CANWIN – Cancer Watch & Intervention Network aims to promote awareness and early recognition of potentially suspicious oral lesions and encourage appropriate professional evaluation.
If you notice a persistent abnormality, don’t wait. Get it examined.
