Ten Dentist-Approved Ways to Improve Your Smile

Health first, appearance second

A smile looks healthiest when teeth are clean and the gums are pink and firm. Most of the things that improve a smile are small habits repeated over months and years, not one-off treatments. The ten points below follow mainstream advice from dental associations and health services, and none of them gives overnight results.

1. Brush twice a day with fluoride toothpaste

Brush for two minutes, morning and last thing at night, with a fluoride toothpaste and a soft brush. Spit out the toothpaste and avoid rinsing with lots of water straight afterwards, so that the fluoride stays on your teeth for longer. Replace the brush or brush head about every three months.

2. Clean between your teeth every day

A toothbrush cannot reach the sides of your teeth. Use floss or interdental brushes once a day. This helps prevent cavities between teeth and bleeding gums. If your gums bleed at first, that usually means they need cleaning more, not less, but ask your dentist if it continues. See why are my gums bleeding.

3. Have a professional clean when advised

Hardened plaque, called calculus or tartar, cannot be brushed off. A dentist or hygienist removes it with scaling and polishing. How often you need this depends on your gums and how quickly deposits build up.

4. Limit sugar and acidic drinks

Sugar feeds the bacteria that cause cavities, and acid from fizzy drinks, squashes and some juices softens enamel. It is the number of times a day you have them that matters most. Keep sugary and acidic foods and drinks to mealtimes, and drink water between meals.

5. Reduce stain-causing habits

Tea, coffee and red wine stain teeth over time, and tobacco does so more strongly, as well as harming the gums. Rinsing with water after a stain-causing drink helps. Stopping tobacco, including chewing tobacco, supari and gutka, is one of the most useful things you can do for your mouth.

6. Treat small cavities and gum problems early

Early cavities can often be treated with a small filling. Left alone, they can reach the nerve and need a root canal. Early gum disease (gingivitis) can be reversed with good cleaning, while advanced disease causes lasting bone loss. Early treatment is simpler, shorter and more comfortable.

7. Look after your saliva

Saliva neutralises acid and helps repair early enamel damage. Drinking water through the day helps. A dry mouth raises the risk of cavities and bad breath, and can be caused by some medicines, so mention it to your dentist.

8. Consider whitening, done with advice

Professional whitening can lighten teeth that have stained or darkened with age. It is not suitable for everyone, as it can cause temporary sensitivity and does not change fillings or crowns. Have cavities and gum problems treated first, and follow the teeth whitening guidance on how long results usually last, which varies from person to person.

9. Ask about straightening and reshaping

Crowded or uneven teeth are harder to clean and may wear unevenly. Braces or clear aligners move teeth over months, and bonding or veneers can reshape chipped or small teeth. These are individual decisions, planned after an examination. Not everyone needs them, and results differ.

10. See your dentist regularly

Most adults are advised to have a check-up at least once a year, and some people need to go every six months or more often. Your dentist decides the interval based on your risk of decay and gum disease. Regular visits catch problems before they cause pain. See how often you should see a dentist.

A realistic view

Changes in colour or shape take weeks or months, and the most lasting improvement comes from keeping teeth and gums healthy. If you are unhappy with how your smile looks, a dentist can explain which options suit you and which do not.
