A Balanced Low-Sugar Diet

Eating Habits

Eating excessive amounts of sugar from snacks, processed foods and drinks not only cause tooth decay, but leads to obesity and increases the risks of diabetes. To safeguard our oral health, you can:

Be Aware of Daily Sugar Intake

Sugar intake in one day
Adult: No more than six teaspoons
Children: No more than three teaspoons

Drink More Water, Take Less Sugar

Avoid sugary drinks, such as soda, juice, energy and sports drinks
Consuming sugary and acidic drinks regularly will damage your teeth

Eat More Fruits & Vegetables, Fewer Snacks

Do not frequently eat sugary snacks, especially between meals
Taking sugar throughout the day increases the risk of developing tooth decay

Develop a good toothbrushing habit

Clean Your Teeth

We have to keep our teeth thoroughly clean by brushing them twice a day, and it can help us prevent oral diseases. To prevent oral diseases, you can:

Brush Your Teeth in the Morning and before Bed at Night

Brush Your Teeth at Morning & before Sleep at Night

Gently move the brush in tiny circles for two minutes
Remember to brush all sides of your teeth, including the outside, the inside, and the chewing surfaces
Do not snack after brushing your teeth at night

Develop a Flossing Habit

Floss at least once a day
Regular cleaning helps to dislodge food in the interdental spaces
Remove the plaque along the gum line to reduce the chance of gum diseases and bad breath

Choose the Type of Toothpaste & Toothbrush that Suits You

Use a fluoride toothpaste and a soft-bristled toothbrush
Replace your toothbrush every three months

Prevent Oral Health Diseases

Healthy Lifestyle

We can prevent oral diseases, maintain good health and reduce the risks of getting other systemic diseases and cancer by building healthy habits. To develop healthy habits, you can:

Avoid Smoking

Having tobacco in any form (smoking or smokeless) will increase the risk of developing oral diseases and oral cancer

Reduce Alcohol Intake

Long-term alcoholic consumption may erode your teeth and lead to tooth decay as it is acidic and contains large amount of sugar

Clean Your Teeth Frequently

Drinking water or chewing sugar-free gum can help keep your mouth clean in addition to toothbrushing

Dental check-up on a regular basis

Visit Your Dentist

Regular dental check-up is vital to maintain good oral health. Dentists can examine our mouth and teeth and advise how to improve our oral health. Having a dental check-up every six months, dentists will:

Visit Dentist Biannually

Educate you how to improve your dental health and maintain good oral hygiene habits

Necessary Treatments & Referrals

Provide necessary treatments and referrals for specific oral health problems, such as severe periodontal diseases or cysts
