Dental issues


1.
After my dentist filled my tooth, they instructed me to clench my teeth.
Later, they manipulated my jaw.
Now, when I relax and close my mouth, my upper teeth touch my lower lip, and sometimes I accidentally bite it.
What could be the reason for this?
2.
I have never encountered a dentist who manipulates the jaw like that.

Dear netizen,
In response to your inquiry, it is common for dentists to check and adjust your bite after a dental filling, which may require you to open and close your mouth.
During the treatment process, if there are any discomforts or misunderstandings due to a lack of explanation, we kindly ask for your understanding and patience.
We recommend that if you have any questions during your treatment, you should feel free to ask your dentist directly, as they will be happy to assist you.

As for accidentally biting your lip, this can happen to anyone.
If you have a sore in your mouth that has not healed for an extended period or if you have other concerns, please consult your dentist for further examination and treatment.
Thank you for your question.

More Info


When it comes to dental issues, particularly the sensation of your upper teeth hitting your lower lip, there are several factors to consider. Based on your description, it seems that this problem may stem from a few potential causes related to dental alignment, jaw function, and possibly the treatment you received from your dentist.

1. Dental Alignment and Occlusion: After dental procedures such as fillings, adjustments to your bite may be necessary. If your dentist instructed you to clench your teeth, it could have been to assess your bite or to help settle the filling material. However, if your bite is misaligned or if there has been a change in your occlusion (the way your teeth come together), this could lead to your upper teeth making contact with your lower lip. Misalignment can occur due to various reasons, including tooth wear, shifting teeth, or changes in jaw position.

2. Jaw Function and Muscle Tension: The act of clenching your teeth can lead to muscle fatigue in the jaw, which may result in a feeling of discomfort or misalignment. If your dentist manipulated your jaw, it could have been an attempt to relieve tension or to realign your bite. However, if the manipulation was excessive or not performed correctly, it might have contributed to your current issue. The muscles that control jaw movement can become tense or fatigued, leading to altered jaw positioning, which may cause your upper teeth to hit your lower lip.

3. Bruxism: If you have a habit of grinding your teeth (bruxism), this could also be a contributing factor. Bruxism can lead to changes in the way your teeth fit together and can cause discomfort in the jaw muscles. If you find yourself clenching your teeth frequently, it may be worth discussing this with your dentist, as it can lead to further complications, including tooth wear and jaw pain.

4. Dental Treatment Follow-Up: It’s important to follow up with your dentist regarding any changes in your bite or discomfort after dental treatments. If your upper teeth are consistently hitting your lower lip, it may indicate that your bite needs to be adjusted. Your dentist can perform a thorough examination and may use techniques such as bite adjustments or orthodontic treatment to correct any misalignment.

5. Seeking a Second Opinion: If you feel uncomfortable with the treatment you received or the techniques used by your dentist, it may be beneficial to seek a second opinion from another dental professional. Different dentists may have varying approaches to treatment, and a fresh perspective could provide you with additional options for addressing your concerns.

In summary, the sensation of your upper teeth hitting your lower lip could be due to misalignment of your bite, muscle tension from clenching, or changes resulting from dental treatment. It’s crucial to communicate these issues with your dentist, who can assess your situation and recommend appropriate treatment options. If necessary, consider seeking a second opinion to ensure you receive the best care for your dental health.
