Here are some ways to relieve pain after a deep teeth cleaning:

1. Take over-the-counter pain medication: Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or acetaminophen can help to relieve pain and inflammation. Be sure to follow the instructions on the medication packaging and to talk to your dentist or doctor if you have any questions or concerns.
2. Use a cold compress: Applying a cold compress to the affected area can help to numb the pain and reduce swelling. To make a cold compress, wrap a few ice cubes in a clean, damp cloth and apply it to the cheek or jaw near the painful tooth for about 10 minutes at a time.
3. Rinse with salt water: Mixing a teaspoon of salt in a cup of warm water and rinsing your mouth with the solution can help to reduce pain and swelling. The saltwater can also help to cleanse the mouth and promote healing.
4. Avoid hot or cold foods and drinks: Hot or cold foods and drinks can cause sensitivity and pain in the teeth after a deep cleaning. It is best to stick to soft, cool, or room-temperature foods and drinks until the pain subsides.
5. Avoid alcohol and tobacco: Alcohol and tobacco can irritate the mouth and can slow down the healing process. It is best to avoid these substances until the pain has subsided.
6. Avoid brushing or flossing vigorously: Vigorous brushing or flossing can irritate the gums and can cause pain after a deep cleaning. It is important to be gentle when brushing and flossing and to avoid applying too much pressure.
7. Avoid touching or poking the gums: Touching or poking the gums can be painful and can cause irritation or infection. It is important to avoid touching the gums with your fingers or any other objects.
8. Talk to your dentist: If the pain persists or becomes severe, it is important to contact your dentist. Your dentist can provide further advice and may recommend additional treatment, such as a pain medication or a mouthrinse.
