Find answers to common questions about dental check-ups, oral hygiene practices, preventive care, and maintaining good oral health.

1 How often should I visit the dentist?

Most dental professionals recommend check-ups and cleanings every six months for preventive care. However, some conditions may require more frequent visits. Your dentist will recommend a schedule based on your specific oral health needs.

2 How often should I brush and floss my teeth?

You should brush your teeth at least twice a day (morning and before bed) for two minutes each time using fluoride toothpaste. Flossing should be done once daily to remove plaque and food particles from between teeth where a toothbrush can't reach. Regular brushing and flossing are the foundation of good oral hygiene.

3 What is the proper way to brush my teeth?

Hold your toothbrush at a 45-degree angle to your gums and use gentle, circular motions to clean all tooth surfaces. Brush for two minutes, making sure to clean the outer, inner, and chewing surfaces of all teeth. Don't forget to brush your tongue to remove bacteria and freshen breath. Avoid aggressive brushing as it can damage gums and tooth enamel.

4 Which toothbrush is better: manual or electric?

Both manual and electric toothbrushes can be effective when used properly. However, electric toothbrushes, particularly those with oscillating-rotating technology, have been shown to remove more plaque and reduce gingivitis more effectively than manual brushes. They can also be helpful for people with limited manual dexterity. The best toothbrush is the one you'll use consistently and correctly.

5 How do I know if I have gum disease?

Common signs of gum disease include red, swollen, or tender gums; bleeding when brushing or flossing; receding gums; persistent bad breath; loose teeth; and changes in how your teeth fit together when biting. Early gum disease (gingivitis) is often painless, which is why regular dental check-ups are important for early detection and treatment.

6 What causes bad breath and how can I prevent it?

Bad breath (halitosis) can be caused by poor oral hygiene, food particles trapped in teeth, dry mouth, tobacco use, certain medications, infections, or systemic diseases. To prevent bad breath, brush and floss regularly, clean your tongue, stay hydrated, avoid tobacco, and visit your dentist regularly. If persistent, consult your dentist as it could indicate underlying health issues.

7 How can I prevent cavities?

Prevent cavities by brushing twice daily with fluoride toothpaste, flossing daily, limiting sugary and acidic foods/drinks, avoiding frequent snacking, using dental sealants (especially for children), drinking fluoridated water, and having regular dental check-ups and professional cleanings. A balanced diet rich in calcium and other nutrients also supports tooth health.

8 What is plaque and why is it harmful?

Plaque is a sticky, colorless film of bacteria that constantly forms on teeth. When you eat or drink, bacteria in plaque produce acids that attack tooth enamel, leading to cavities. Plaque can also harden into tartar (calculus), which can cause gum disease. Regular brushing and flossing help remove plaque before it can cause damage.

9 Why do my teeth feel sensitive and what can I do about it?

Tooth sensitivity occurs when the tooth's protective enamel is worn down, exposing the underlying dentin which contains tiny tubes connected to nerves. This can be caused by brushing too hard, gum recession, acidic foods, teeth grinding, or dental procedures. Solutions include using desensitizing toothpaste, soft-bristled toothbrushes, fluoride treatments, and addressing underlying issues like grinding or acid reflux.

10 Is teeth grinding (bruxism) harmful?

Yes, teeth grinding or clenching (bruxism) can cause significant damage over time, including worn tooth enamel, flattened or chipped teeth, increased tooth sensitivity, jaw pain, and headaches. It can also lead to TMJ disorders. If you grind your teeth, your dentist may recommend a night guard to protect your teeth during sleep, along with stress reduction techniques if stress is a contributing factor.

11 What are dental sealants and who should get them?

Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth (molars and premolars) to prevent decay. They seal off the deep grooves where food particles and bacteria often get trapped. Sealants are particularly recommended for children and teenagers, ideally soon after their permanent molars erupt, but adults without decay or fillings in their molars can benefit as well.

12 How does diet affect oral health?

Diet significantly impacts oral health. Sugary and acidic foods and beverages contribute to tooth decay and enamel erosion. Frequent snacking increases the time teeth are exposed to acid attacks. A balanced diet rich in calcium, phosphorus, vitamin D, and vitamin C supports healthy teeth and gums. Crunchy fruits and vegetables can help clean teeth surfaces, while drinking water rinses away food particles and bacteria.
