If you want to know how to remove yellow stains on teeth, the most effective option is an in-practice whitening treatment with your dentist. Professional whitening has become very popular because you can see a difference in a single visit or a few visits, they also give long-lasting teeth whitening results. Whitening treatments with your dentist are typically more expensive than whitening products you can buy in shops.
If you don’t want to make multiple visits to your dentist for teeth whitening, an alternative is to try it at home. With this method, it’s always advised that you follow advice from your dentist before beginning your treatment. It’s likely you’ll make an initial appointment with your dentist to take impressions of your mouth to make a custom-fitted mouthguard. Once you have your reusable mouthguard, you can buy the whitening solution from your dentist to carry out the treatment yourself. The whitening gel supplied by dentists is stronger than over-the-counter products, so make sure you follow their instructions on how long and how often you should use it to achieve the results you're looking for.
