Having a cavity can be awfully uncomfortable. While some cavities can be treated with fillings, others require root canal therapy. So, how do you know which you need?

Key takeaways:

– Fillings are enough if the cavity is normal sized and is not accompanied by pain.

– You’ll only need a filling if the cavity is not painful, which means it has not progressed into the third layer of the tooth.

– Root canal is necessary if the cavity has reached the pulp and your teeth are discoloured or sensitive.

– A root canal procedure will end the intense pain.

Consult your dentist for the best treatment for you.
