Call the dentist to get rechecked.
Try neem toothpaste. It does not have fluoride, but you could still use it once or twice a day, switching off with fluoride toothpaste.
It is very important to keep your teeth clean and follow your dentist's instructions.
Mint can aid oral healing. Try mint tea. There are herbs as well, such as cloves.
Thankyou for your reply i have purchased some neem toothpaste & im going to give it ago.
It would be a good idea to see your dentist to check that everything is fine as you may still have an infection.
Try rinsing your mouth with salty water, or an antibacterial mouth wash to see if that helps.
Best wishes.
