2. Can I thoroughly clean my teeth by daily toothbrushing?
Brushing alone doesn't thoroughly clean the teeth because toothbrushing can only clean the outer surface, inner surface, and chewing surface of teeth. In order to thoroughly clean dental plaque from the adjacent surfaces of the teeth, dental floss must be use every night.

3. How can I keep my teeth healthy?
In order to keep your tooth and gum healthy, you can refer to the "Oral Care Tips"

4. If I rinse my mouth after every meal, does it help to reduce the chances of getting dental caries?
Every time after we eat, the bacteria inside dental plaque will break down the sugars from our food to form acid, causing the pH to decrease in our mouth. When our mouth's pH is lower than pH5.5, the minerals at the surface of our teeth will slowly dissolve.
It takes 30 minutes for the saliva to neutralize the acid and redeposit the lost minerals. If we eat frequently, the pH in our mouth will consistently be low, leaving insufficient time for the saliva to remineralize our teeth. The minerals at the surface of our teeth will continuously be lost, and eventually cause dental caries.
Every time when you eat, your teeth are exposed to acidic attack. Saliva can neutralize the acid but rinsing cannot. Therefore, rinsing after meals does not help to reduce the chances of dental caries. If you want to prevent dental caries, you must reduce the frequency of food and drinks intake.

5. How can I prevent Periodontal Disease?
To prevent Periodontal Disease you have to:
1. Brush your teeth in the morning and before bed at night to remove the dental plaque.
2. Clean the adjacent tooth surfaces everyday by dental flossing
3. Not to smoke or quit smoking
4. Have a dental check-up at least once a year for early diagnosis and treatment of Periodontal Disease

6. How can I clean off the stain on my child's teeth? Can I bring her to a dentist for scaling?
Thoroughly clean the infant's teeth daily, avoid feeding food that can cause stain and bring the child to a dentist regularly for scaling are all methods to minimize tooth staining. Please refer to the "Discoloration of teeth" section of this website.
You can schedule a dental appointment for your child when the first deciduous tooth is erupted. The dentist can understand the oral condition of your child and decide whether scaling is needed. You should also be patient when brushing for your child. For related pointers, please refer to the booklets Brushing Teeth is what children can do and Begin Dental Check-up Early in Age.
