Tooth Pain When Lying Down After Dental Treatment - Dentistry

Experiencing pain while lying down after receiving a nerve block injection?


Hello, doctor.
I would like to ask about my recent dental issue.
When I lie down, my teeth start to hurt, but it feels much better when I sit up or drink something cold.
However, in the past, drinking cold beverages would make my teeth very sensitive.
I visited the dentist today, and he only prescribed medication and asked me to come back in a week.
Is it normal for me to still feel pain when lying down?

If you experience tooth pain that does not improve after taking medication, it may indicate inflammation of the dental nerve or periodontal tissue.
It is advisable to consult a dentist for further treatment.

More Info


Tooth pain, especially when lying down, can be a distressing experience and may indicate several underlying issues related to dental treatment. Based on your description, it seems that you are experiencing discomfort that is alleviated when sitting up or consuming cold beverages, which is a common symptom associated with dental problems.

Firstly, it's important to understand that after dental treatments, especially procedures like root canal therapy, it is not uncommon to experience some level of discomfort or pain. This pain can be due to inflammation in the surrounding tissues, residual sensitivity in the tooth, or even issues related to the bite alignment after the placement of crowns or fillings. When you lie down, the change in position can increase blood flow to the area, potentially exacerbating the pain.

The fact that you mentioned the pain decreases when you sit up or drink something cold suggests that there may be an element of nerve sensitivity or inflammation involved. Cold beverages can temporarily numb the area and reduce inflammation, providing relief. However, if you previously experienced sensitivity to cold, this could indicate that your tooth is still reacting to the treatment or that there is an underlying issue that needs to be addressed.

In your case, since the dentist only provided medication and scheduled a follow-up appointment for a week later, it is crucial to monitor your symptoms closely. If the pain persists or worsens, or if you experience additional symptoms such as swelling, fever, or difficulty chewing, it is advisable to contact your dentist sooner rather than later. Persistent pain could indicate complications such as an infection, improper sealing of the root canal, or issues with the dental crown or filling.

Here are some steps you can take to manage your discomfort in the meantime:
1. Pain Management: Continue taking any prescribed pain relief medication as directed. Over-the-counter options like ibuprofen or acetaminophen can also help manage pain and reduce inflammation.

2. Cold Compress: Applying a cold compress to the outside of your cheek can help reduce swelling and numb the area, providing temporary relief.

3. Avoid Certain Foods: Steer clear of very hot, cold, or hard foods that might aggravate the pain. Stick to soft foods that require minimal chewing.

4. Good Oral Hygiene: Maintain good oral hygiene by gently brushing and flossing around the affected area to prevent any additional irritation or infection.

5. Follow-Up: Keep your follow-up appointment, but do not hesitate to reach out to your dentist if your symptoms do not improve or if they worsen.

In summary, while some discomfort after dental treatment is normal, persistent pain, especially when lying down, warrants further evaluation. It is essential to communicate openly with your dentist about your symptoms and any changes you experience. If necessary, seeking a second opinion from another dental professional may provide additional insights and treatment options. Remember, your comfort and health are paramount, and addressing these concerns promptly can lead to better outcomes.
