Most cavities in teeth are treated with a simple filling but more severe cases may require root canal treatment. As soon as you notice a cavity, or suspect one is present, you should have it seen to by your dentist as the problem will not simply disappear of its own accord.
Root canal treatment may be required if:
– The tooth is discoloured
– The tooth is painful or very sensitive
– The cavity has cracked a tooth
The good news is that having a filling is “a relatively simple procedure” and painless. More information on the difference between a filling and root canal treatment can be found at https://yourdentalhealthresource.com/is-a-filling-okay-or-will-i-need-a-root-canal/.
