What is the best way to completely whiten my teeth and fix them that is not too expensive? i for years ate lemons and lots of hot spicy foods and my teeth are now stained yellow and are brittle with mini cracks in them. also my inner mouth is peeling all

I : I think this might be a better question for a dentist and probably will require an oral examination. There are a few conditions such as lichen planus that can affect the oral mucosa and cause white patches. Also, are you a smoker? This certainly would put you at risk for oral cancer (such as squamous cell carcinoma). Read more about lichen planus at the link below.

It : It is very imortant to have a thourough dental examination before any cosmetic work. The exam should include teeth and oral tissues. The dentist might recommend an exam by an oral medicine specialist if he is concerned with peeling of your gums to rule out autoimmune diseases that can cause that.

Big Challenge: You are indicating some serious possible dental problems and you want a beautiful white smile that is inexpensive. That is like going to the dealership and asking for a new cadillac but only wanting to spend $500 on it. My challenge to you is to get a dentist consultation with all necessary xrays and determine the extent of your problems first. You may have some other issues that take precedence.
