Mam,you need to visit a cosmetic dentist to get your teeth evaluated.We can then provide you with minimally invasive treatment plans like microabrasion or lumineers to solve your problem.Regards,Dr Suman Makam,Dental ARts,Jayanagar,Bangalore.
Please visit your nearest Dentist for a proper consultation. It is probably nothing serious and can be fixed by change of Drinking Water supply as the water could contain excess Flourides.
1. Drink Bottled water or RO purifier Water ( Aquaguard and similar companies)
2. Consult your dentist for Cosmetic Treatment (As per Dentists Suggestion)
3. Ask for Partial Veneers for just the affected teeth.
Note : There is nothing better than God given Natural Teeth. Always ask your Dentist for Natural Cures before opting for Veneers (Depending on condition of tooth).
