A. Hi, Sorry it has taken me so long to respond.It sounds like the nerve in your tooth has died. This means you will either need a root canal treament, or, it means the tooth will need to be exracted. Of course it’s very important to keep all of your teeth but depending on your budget and what your preference is – root canal treatment is your best option.We do have an Endodontist who works with us named Raquel, she specialises in Root canal treatment and works every second Monday.Depending on the tooth that requires treatment, the cost of root canal treatment ranges between £595 – £695 – not including the filling that you require after the treatment.
