Gum Swelling and Molar Alignment Issues - Dentistry

More Info

---

It sounds like you're experiencing a couple of dental issues that are causing you concern, specifically gum swelling and alignment of your molars. Let's break down your questions and provide some insights based on dental health knowledge.


Gum Swelling and Changes
Firstly, the swelling of your gums, particularly on the right upper side, followed by a breakdown of the tissue (the "破皮" you mentioned), could be indicative of several conditions. The most common causes of gum swelling include:
1. Gingivitis: This is an inflammation of the gums often caused by plaque buildup. Symptoms include redness, swelling, and bleeding when brushing or flossing.

2. Periodontitis: If gingivitis is left untreated, it can progress to periodontitis, which is a more severe form of gum disease that can lead to tooth loss.

3. Abscess: A localized infection in the gum can cause swelling and pain. This might also lead to the formation of pus, which could cause the tissue to break down.

4. Allergic Reaction or Irritation: Sometimes, certain foods, dental products, or even hormonal changes can cause temporary gum swelling.

The fact that the swelling moved from one side to the other could suggest a few things. It might be related to your oral hygiene practices, dietary habits, or even a reaction to something you consumed. It's also possible that the initial swelling was due to localized irritation that then spread or was exacerbated by other factors.


Alignment of Molars
Regarding your second question about the alignment of your molars, particularly the upper molars being longer on the outside compared to the inside, this can be a common occurrence. Here are some points to consider:
1. Natural Variation: It is not uncommon for molars to have slight variations in height and alignment. The upper molars can sometimes appear to be longer on the buccal (outer) side due to their anatomical structure.

2. Tooth Wear: Over time, teeth can wear down unevenly due to grinding (bruxism), misalignment, or other factors. This can lead to discrepancies in height.

3. Orthodontic Issues: If your molars are misaligned, it could be a sign of a more significant orthodontic issue. If your upper molars are not properly aligned with your lower molars, it could lead to problems with bite and jaw alignment.

4. Post-Extraction Changes: Since you mentioned that you have had your wisdom teeth (智齒) removed, the surrounding teeth may shift slightly over time, which can affect alignment.


Recommendations
Given your symptoms, here are some recommendations:
1. Maintain Oral Hygiene: Ensure you are brushing at least twice a day and flossing daily to reduce plaque buildup and prevent gum disease.

2. Follow Up with Your Dentist: Since you have already seen a dentist, it would be wise to return if the swelling persists or worsens. They may want to perform a deeper cleaning or assess for any underlying issues like an abscess.

3. Monitor Changes: Keep an eye on the alignment of your molars. If you notice significant changes or discomfort, consult with an orthodontist for a professional evaluation.

4. Consider Dietary Factors: Sometimes, certain foods can irritate the gums. If you notice a pattern, try to identify any potential triggers.

5. Stay Hydrated: Drinking plenty of water can help maintain saliva production, which is essential for oral health.

In conclusion, while some gum swelling can be a normal response to irritation or infection, persistent or recurrent issues should be evaluated by a dental professional. Similarly, variations in tooth height can be normal, but if they cause discomfort or functional issues, further assessment may be necessary. Always prioritize your dental health and seek professional advice when in doubt.
