Teeth Whitening: How Long Does it Last?
Making your smile more attractive is a lot easier with a teeth-whitening procedure. It can lighten the colour of your natural teeth and remove stains from smoking, old age, and bad lifestyle habits. This can be in the form of custom trays or laser whitening, which can both provide desirable results. Laser or power whitening is said to make your smile up to five shades lighter.
Longevity of Whitening
The most common concern about the procedure is the longevity of the whitening effect. The Oral Health Foundation notes that the effects can last up to three years, but this will vary from every patient. Your teeth will stay whiter longer if you don’t smoke or avoid foods and drinks that can stain teeth. London cosmetic dentistry centres like Fresh Dental note that proper oral hygiene also plays a role in keeping your smile whiter.
Studies suggest that many of the patients report results that last from nine to 12 years, while some notice the difference in their teeth colour after three years. It is unlikely to see a regression in the shade within the first year, but habits and food choices will still play a part. If you’re considering whitening, dentists recommend taking care of your teeth after the procedure.
- Brush your teeth twice a day using fluoride toothpaste (you can also use a whitening toothpaste)
- Limit consumption of sugary and acidic foods and beverages
- Avoid foods that can stain teeth such as tea, coffee, wine, dark-coloured juices, cola, and tomato-based sauces
- Visit your dentist for regular checkups and cleanings
Keep in Mind
It is important to know that teeth whitening only works on natural teeth. It will not work on veneers, crowns, and dentures. This is because the bleaching component has no effect on porcelain surfaces. If you have stained or discoloured dentures, for instance, you will need to consult your dentist to know how you can whiten them.
If you’re thinking of whitening your teeth, talk to your dentist to know the procedures available. Ask about the results and how long the whitening effect will last. This will help you prepare better for the treatment and have realistic expectations.
