Hi I'm 38, my teeth are in good condition however I broke a canine 12 years ago due to grinding. I was advised at the time to leave it but it has become painful. I'm currently undergoing root canal but my dentist is ensure he will be able to complete it as there is calcification, he applied something to try and wear this away and am due a follow up. If I lose the tooth what is the best option for replacement? And what option can be implemented while pregnant?
