Teeth whitening to remove tobacco stains
Although long-term smoking has made it challenging to have tobacco stains removed from teeth, there are still ways to try and achieve acceptable results.
To make your teeth whiter and remove those yellowish stains, you can consider professional teeth whitening, at-home treatments, or over-the-counter (OTC) teeth whitening products.
1.Professional Teeth Whitening
When the tobacco stains have penetrated deep into layers of dentin, whitening toothpaste or DIY (do-it-yourself) remedies will no longer work, and seeking professional teeth whitening is essential.
InChair teeth whitening
After examining your teeth thoroughly and ensuring that the procedure is suitable for you, your dentist or oral hygienist will start the process by determining your desired final shade.
Teeth whitening might not be a suitable option for tooth sensitivity or thin or transparent teeth.
- During the procedure, your oral hygienist will place a cheek retractor into your mouth, which exposes all visible teeth when you smile.
- Then a special protective resin or gel will be applied over your gums to protect them from burning caused by peroxide (the bleaching gel).
- The dentist will apply the bleaching gel to your teeth and leave it for about thirty minutes.
- Laser light is usually used to speed up the process.
- The oral hygienist will remove the previous bleaching gel, apply fresh gel, and leave it again for another thirty minutes.
- After the protective guard is removed, you should rinse and see the result of whitening.
Your dentist may give you a custom take-home tray to use as a follow-up treatment to your professional teeth whitening session.
Keep in mind that teeth whitening is not permanent, and your teeth are still in danger of getting discoloured if you continue smoking.
2.At-Home Teeth Whitening
At-home teeth whitening options are also available for those who prefer to use more convenient ways to restore their teeth’ colour.
Professional take-home whitening kit
Tray-based tooth whitening kits come in two types: one-size-fits-all store-bought kits and custom-fitted.
Custom-fitted take-home whitening kit
- Your dentist will take impressions of your upper and lower teeth for a custom-fabricated tray.
- The impression will be sent to a dental lab to fabricate custom-made whitening mouth trays.
- After your custom-fitted mouth tray is prepared, you will come to the office, and your dentist will give you a carbamide peroxide-based gel rather than a hydrogen peroxide-based bleaching gel or paste to place in the tray.
- You will receive the necessary instructions on applying the solution on the tray to get the result.
- Your dentist may ask you to wear the mouth tray for one to several hours a day for up to 28 days.
Note: Although you will need to be more patient to get your desired result with carbamide peroxide-based gel than a hydrogen peroxide-based gel, it will cause less sensitivity for your gums or tongue.
Over-the-counter trays will also help you with your discoloured teeth; however, they may not be as effective and convenient as custom trays.
As the name suggests, OTC trays may not fit perfectly over your teeth because they are not specially made for you.
