Deep Cavities in Molars: Symptoms and Care

Q: Deep Cavities in Molars: Symptoms and Care

Hello： If a cavity has formed, it is recommended that you promptly visit a hospital or clinic to have the cavity filled. <br>Thank you.

Cavity in molars

Hello Doctor, I noticed a fairly deep cavity in one of my molars while using a dental floss stick.
When I pressed harder, I felt a slight sensitivity but no pain.
I also dislodged a small yellow hard piece (which looked like a part of the tooth) and two or three small black debris.
After that, I checked again and didn’t find anything else.
In the past, that tooth had also lost a small fragment that resembled a part of the tooth while biting down on a hard seed.

More Info

When it comes to deep cavities in molars, it's crucial to understand the symptoms, potential complications, and appropriate care. Based on your description, it sounds like you may be experiencing a significant dental issue that requires attention.

Symptoms of Deep Cavities
1. Sensitivity: As you mentioned, you feel a slight acidic sensation when probing the cavity, which is a common symptom of tooth decay. This sensitivity can occur when the cavity reaches the dentin, the layer beneath the enamel, which is more sensitive to temperature and pressure.

2. Visible Changes: The presence of a yellow hard substance and black debris suggests that there may be decay or a broken piece of the tooth. The yellow material could be plaque or calculus, while the black spots might indicate the presence of decay.

3. Pain: While you are not currently experiencing pain, deep cavities can sometimes be asymptomatic until they reach the pulp of the tooth, leading to more severe issues such as infections or abscesses.

4. Previous Damage: The fact that you have previously lost a small piece of the tooth while biting down on something hard indicates that the structural integrity of the tooth may already be compromised, making it more susceptible to further decay.

Care and Treatment Options
1. Dental Evaluation: It is essential to schedule an appointment with a dentist as soon as possible. They will perform a thorough examination, possibly including X-rays, to assess the extent of the decay and determine the best course of action.

2. Fillings: If the cavity is not too deep and has not reached the pulp, the dentist may recommend a filling. This involves removing the decayed portion of the tooth and filling it with a suitable material to restore its function and prevent further decay.

3. Root Canal Treatment: If the decay has progressed to the pulp, a root canal may be necessary. This procedure involves removing the infected pulp, cleaning the inside of the tooth, and sealing it to prevent future infection.

4. Crowns: In cases where a significant portion of the tooth is damaged, a crown may be placed over the tooth to restore its shape, size, and function.

5. Preventive Care: After treatment, maintaining good oral hygiene is crucial. This includes regular brushing and flossing, using fluoride toothpaste, and visiting the dentist for routine check-ups and cleanings.

6. Dietary Considerations: Avoiding hard foods that could further damage the tooth is advisable. Additionally, reducing sugar intake can help prevent further cavities.

Conclusion
Deep cavities in molars can lead to serious dental issues if not addressed promptly. While you may not currently be experiencing significant pain, the symptoms you describe indicate that professional evaluation is necessary. Early intervention can prevent more extensive and costly treatments in the future. Remember, maintaining good oral hygiene and regular dental visits are key to preventing cavities and ensuring overall dental health.
