Common Dental Concerns: Sensitivity, Cracks, and Rough Edges Explained

Questions about teeth?

Hello Dr.
Chiu,
I have some questions regarding my teeth that I would like to ask you:
Q1.
My lower left incisor has become sensitive and feels dull pain after being lightly struck by a metal utensil.
The tooth appears normal to the naked eye, but when illuminated, I can see vertical fine lines on its surface (which I believe are dental cracks).
Currently, I experience no discomfort when eating or with hot and cold stimuli.
I have my teeth cleaned and checked every six months, and the dentist has not indicated any cavities in that tooth.
Based on this description, Dr.
Chiu, what do you think could be causing the sensitivity and dull pain in my lower left incisor after being struck by the metal utensil?
Q2.
I have several teeth with rough or angular areas on the occlusal surfaces, but they are not sharp enough to cause injury to my tongue or oral mucosa.
Dr.
Chiu, can I ask my dentist to smooth and polish the rough or angular areas on those teeth? Or should I allow the rough or angular areas to naturally wear down over time without any intervention, as it may not be advisable to grind down teeth arbitrarily? I would appreciate your guidance on this matter.
Thank you, Dr.
Chiu.

Dear Patient,
Thank you for your questions regarding your dental concerns. Let's address each of your queries in detail.

Q1: Sensitivity and Pain in Your Lower Left Incisor
The sensitivity and dull pain you experience in your lower left incisor after it was struck by a metal utensil could be attributed to several factors. Although the tooth appears normal externally, the presence of vertical fine lines (which you suspect to be cracks) can indicate underlying issues. These cracks, often referred to as "craze lines," can develop due to trauma, excessive biting forces, or even thermal changes from hot and cold foods.
Even if you do not currently experience discomfort while eating or drinking, the sensitivity could be a sign of a more significant problem, such as a cracked tooth syndrome. This condition can lead to pain when chewing or when the tooth is subjected to temperature changes. It is crucial to monitor the tooth for any changes in sensitivity or pain. If the symptoms persist or worsen, I recommend consulting your dentist for further evaluation, which may include X-rays or other diagnostic tools to assess the integrity of the tooth structure.

Q2: Rough or Jagged Edges on Chewing Surfaces
Regarding the rough or jagged edges on the occlusal surfaces of some of your teeth, it is generally advisable to have these areas smoothed and polished by a dental professional. While natural wear can occur over time, it is not always sufficient to address roughness that may lead to discomfort or potential injury to your tongue or oral mucosa.
Your dentist can safely perform a procedure known as occlusal adjustment, where they will carefully grind down the rough areas to create a smoother surface. This not only enhances comfort but can also improve your bite and overall dental function. It is important to avoid excessive self-treatment or attempting to smooth the teeth on your own, as this can lead to further damage or complications.

In summary, both of your concerns highlight the importance of regular dental check-ups and open communication with your dentist. If you notice any changes in sensitivity, pain, or the condition of your teeth, do not hesitate to reach out for professional advice. Maintaining good oral hygiene and addressing issues promptly can prevent more severe complications in the future.

If you have any further questions or need clarification on any points, please feel free to ask. Your dental health is important, and I am here to assist you.

Best regards,
Dr. Qiu
