If the tooth is extremely sensitive to hot or cold, antibiotics will not help. The decay must be removed and filled.
The following home measures may help make symptoms manageable until care can be accessed:
- Good cleaning with fluoride toothpaste
- Reduce sugar intake, to prevent decay getting any worse.
If there is a hole in the tooth, or a tooth has cracked and is now sensitive/sharp, a temporary filling can be packed into the space. These are widely available from supermarkets and pharmacies.
