Regarding tooth grinding?


Dear Dr.
Tseng,
I have a slightly uneven area on the outer edge of my upper right second premolar, and a slightly sharp area on the outer edge of my upper right second molar.
Currently, neither tooth has cavities, and they do not scrape against my tongue or the mucosa in my mouth, nor do I have any issues with chewing.
Due to the slight unevenness and sharpness of these two teeth, I would like to see a dentist to use dental instruments to smooth them out and make them less sharp.
My main concern about the unevenness and sharpness is that they may be more prone to chipping or breaking during chewing.
I have the following questions for you, Dr.
Tseng:
Q1.
Based on the above, in the absence of any issues with the teeth, do you think it is appropriate to smooth out the uneven and sharp edges of the teeth?
Q2.
Following up on the previous question, should teeth that are not problematic be left alone and not be ground down? Will the unevenness and sharpness naturally wear down over time through normal wear?
Q3.
Dr.
Tseng, will grinding down healthy teeth damage the tooth structure and affect the integrity of the teeth, making them more fragile?
Q4.
I am concerned that the slight unevenness and sharpness of my teeth may lead to them chipping or breaking more easily during chewing.
Is this concern valid?
Thank you, Dr.
Tseng.

Hello: 1.
If there is no abrasion on the tongue or oral mucosa, it is not recommended to grind the teeth, but consideration should be given to whether the unevenness and sharpness of the tooth edges are caused by misalignment of the teeth.
2.
During the natural wear process, the uneven or sharp areas of the teeth may gradually be worn down.
3.
Healthy teeth will damage the outer enamel layer, and if the inner dentin is exposed, the teeth may become sensitive and painful.
4.
It is advisable to consult a dentist for an examination to identify the causes of the unevenness and sharpness of the teeth.

When it comes to dental care, particularly regarding the smoothing of uneven teeth, there are several important considerations to keep in mind. Your concerns about the slight irregularities and sharp edges on your teeth are valid, and it’s great that you’re being proactive about your dental health. Let’s address your questions one by one.

Q1: Is it appropriate to smooth out the uneven and sharp edges of teeth that are otherwise healthy?
In general, if the teeth are healthy and not causing any discomfort or functional issues, it may not be necessary to perform any alterations. However, if the irregularities are causing you concern about potential future problems, such as fractures or discomfort during chewing, it may be reasonable to discuss smoothing them out with your dentist. Dentists often use a technique called "tooth contouring" or "tooth reshaping" to address minor imperfections. This procedure can enhance the aesthetics of your smile and improve comfort.

Q2: Should healthy teeth be left alone, or will natural wear smooth them over time?
Teeth do undergo natural wear and tear over time, and minor irregularities may become less pronounced as you continue to use them. However, this process can be slow, and if the sharp edges are a concern, it might be better to address them sooner rather than later. Leaving them as they are could potentially lead to issues down the line, such as increased wear on opposing teeth or discomfort.

Q3: Will smoothing healthy teeth damage the enamel or affect their structural integrity?
Tooth enamel is the hardest substance in the human body, but it can be affected by excessive grinding or aggressive polishing. A skilled dentist will take care to only remove a minimal amount of enamel when contouring teeth, which should not compromise the tooth's integrity. However, it’s crucial to ensure that the procedure is performed by a qualified professional to avoid any unnecessary damage.

Q4: Is it correct to be concerned that uneven or sharp teeth may lead to fractures during chewing?
Yes, your concern is valid. Teeth with sharp edges or significant irregularities can be more prone to chipping or fracturing, especially under pressure from chewing. If you feel that the irregularities could lead to such issues, it would be wise to consult with your dentist. They can assess the situation and determine if smoothing the edges is a prudent course of action.

In conclusion, while it’s often best to leave healthy teeth alone, your concerns about the potential for fractures and discomfort are legitimate. Consulting with a dentist who can evaluate your specific situation is the best way to determine the appropriate course of action. They can provide you with tailored advice based on the condition of your teeth and your overall oral health. Regular dental check-ups and cleanings are also essential to maintain good oral hygiene and catch any potential issues early on. Remember, maintaining a healthy diet, practicing good oral hygiene, and avoiding habits like grinding your teeth can also contribute significantly to your dental health.
