A: Many people do not realize that everyone’s teeth are different, and some take to whitening and others do not. So, before you spend a lot of money on a pricey procedure, try an over-the-counter kit to make sure your teeth will take to whitening. If you decide that you are a candidate, seek treatment at a reputable dentist office. And, most importantly, follow the guidelines of food restrictions. If you go back to drinking lots of coffee and red wine, your white teeth will lack luster once again. Good luck, and I hope this answer will make you smile.
A: There are distinct reasons teeth darken: naturally, they tend to get yellowish with age but any food that stains your clothes stains teeth like red sauce, red wine, coffee., etc.
An easy solution to keep from getting teeth yellow is to keep good home care.
There are inexpensive options for whitening teeth such whitening toothpaste and OTC bleaching systems, but they are not recommend due to potential damage they can cause to teeth like abrasion leading to tooth sensitivity as one example.
Dental offices have the best options available because the treatment is designed for each patient with a better outcome in mind.
Bleaching teeth is not predictable because it depends on tooth structure, saliva flow, eating and drinking habits and quality of the product.
My advice is to consult with a dentist for an informed decision before moving forward with treatment.
