A

For the rest of today avoid:

  • Mouthwashing
  • Spitting out
  • Hot food and drinks
  • Alcohol
  • Smoking
  • Exercise or effort for the next 24hrs

From tomorrow:
- Rinse your mouth with an antiseptic mouthrinse or hot salt water, so just put a teaspoon of table salt in a mug of hot water. Do this every 4 hours and after meals. Do this until the area has healed.

You may get a small amount of bleeding the next few days. If it’s persistent, apply pressure to the area by biting down hard on a rolled up clean handkerchief or cloth for 10 minutes. After this, do not rinse out for a further 12 hours. If the bleeding doesn’t stop after doing this, contact us.

Discomfort can also be expected and there may be some swelling. Simple pain relief tablets, such as paracetamol or what you would usually take for a headache are recommended. Your local pharmacist can advise you on pain relief if needed.

If you have any concerns, don’t hesitate to contact us.
