Consequences of Ignoring a Deep Cavity in Your Tooth - Dentistry

Dental issues


My mother has been having her lower left last tooth treated for cavities for a long time, but it still hurts.
The dentist keeps applying medication.
That tooth has been drilled out almost halfway.
What will happen if she doesn't go back for a filling?

Lai, 10~19 year old female. Ask Date: 2008/06/30

Hello Sir: Thank you for your inquiry.
Here are my responses and suggestions:
1.
Deep cavities are not suitable for direct filling.
It is advisable to first address the sensitivity symptoms and wait for them to subside before proceeding with a permanent filling.
If there is already gingival inflammation, even after filling, if there are still symptoms of pain, root canal treatment should be considered.
After the root canal procedure is completed, the cavity can be filled, and a crown can be placed to restore normal chewing function.

Finally, I wish you peace and happiness!

Ignoring a deep cavity in your tooth can lead to a series of serious dental and health complications. When a cavity is left untreated, it can progress deeper into the tooth structure, affecting not only the enamel and dentin but also reaching the pulp, which contains nerves and blood vessels. This progression can result in several consequences:
1. Infection and Abscess Formation: As the cavity deepens, bacteria can invade the pulp, leading to pulpitis (inflammation of the pulp). If the infection is not addressed, it can result in the formation of a dental abscess, which is a pocket of pus that can cause severe pain and swelling. An abscess can also lead to systemic infections if the bacteria enter the bloodstream.

2. Tooth Loss: A tooth that has been extensively damaged by decay may become non-restorable. If the structure of the tooth is compromised to the point where it cannot support a filling or crown, extraction may be the only option. Losing a tooth can have significant implications for your overall oral health, including shifting of adjacent teeth, bite problems, and difficulties with chewing.

3. Pain and Discomfort: As the cavity progresses, it can cause increasing pain, especially when chewing or when exposed to hot or cold temperatures. This discomfort can significantly affect your quality of life, making it difficult to eat or concentrate on daily activities.

4. Impact on Surrounding Teeth: A deep cavity can also affect neighboring teeth. The bacteria from the decayed tooth can spread to adjacent teeth, leading to further decay and complications. Additionally, if the tooth is lost, the surrounding teeth may shift, leading to misalignment and bite issues.

5. Systemic Health Issues: There is growing evidence linking oral health to overall health. Chronic dental infections can contribute to systemic conditions such as heart disease, diabetes, and respiratory infections. The bacteria from an untreated cavity can enter the bloodstream, potentially leading to serious health complications.

6. Increased Treatment Complexity and Cost: Delaying treatment for a deep cavity often results in more complex and costly procedures down the line. What could have been a simple filling may escalate to a root canal treatment or extraction, followed by the need for implants or bridges to replace the lost tooth.

Given your mother's situation, where the tooth has been treated multiple times but remains problematic, it is crucial to seek further evaluation from a dental professional. If the tooth has been "almost hollowed out," it may be at risk of fracture or may no longer be viable for restoration. The dentist may recommend imaging studies, such as X-rays, to assess the extent of the decay and determine the best course of action.

In summary, ignoring a deep cavity can lead to severe pain, infection, tooth loss, and broader health issues. It is essential to address dental problems promptly to maintain oral health and prevent complications. If your mother is experiencing ongoing pain and her tooth has been significantly compromised, it is advisable to consult with a dentist who can provide a thorough examination and discuss potential treatment options, which may include filling, root canal therapy, or extraction, depending on the condition of the tooth.
