You should see a dentist to identify the cause of your tooth pain, which may be due to cavities, gum disease, a dental abscess, or an infection. Maintain good oral hygiene and avoid very hot, cold, or sugary foods. You may take paracetamol or ibuprofen to manage the pain and rinse your mouth with warm salt water to help reduce inflammation until you are examined.

This sensation may be due to excess mucus from a throat infection, allergies, acid reflux, sinus drainage, or dehydration. You should consult your doctor to find out the exact cause. Do not try to clear it yourself, as this may irritate your mouth. Drink plenty of fluids, gargle with warm salt water, and avoid irritants like smoke until you are examined.

Persistent gum bleeding after a dental cleaning is often due to ongoing gum inflammation, plaque build-up, or early gum disease. Brush gently twice daily with a soft toothbrush, floss regularly, and consider using antiseptic mouthwash (such as chlorhexidine) as advised by your dentist. If the bleeding does not stop or worsens, please see your dentist for a review and further treatment.

You should see your doctor or dentist as soon as possible, as being unable to open your mouth may indicate a serious infection, a jaw injury, or a problem with the jaw joint. Do not try to force your mouth open, as this could cause further damage. Eat soft or liquid foods and chew slowly to avoid straining your jaw until you are examined.

Rinse your mouth with salt water or an antiseptic mouthwash and apply a protective or anaesthetic gel. Avoid spicy or acidic foods and maintain good oral hygiene to help it heal faster. If the ulcer persists for more than two weeks or is very painful, please see a doctor or dentist.
