Q. Hello, my right front tooth has over the years has become darker in colour and quite sensitive, I’m guessing its rotting as the enamel is crack . It is sensitive to brushing and cold drinks. What would be the best option to fix the tooth, my other teeth aren’t the greatest either but no where near as bad. I know teeth are important but fixing them are very expensive and money is not available, basically I want to be able to smile confidently without spending alot of money. Thanks for reading.
