When it comes to oral health, it's understandable to have concerns about symptoms that may seem alarming, especially when they involve pain, discomfort, or unusual changes in the mouth. Based on the information you've provided, let's address your concerns regarding occasional biting or friction in the mouth and its potential implications for oral cancer.

Firstly, the symptoms you describe—occasional biting or friction in the area of your left posterior molar, leading to minor bruising that heals within a few days—are not typically indicative of oral cancer. Oral cancer often presents with more persistent symptoms, such as non-healing ulcers, lumps, or growths in the mouth, changes in the color or texture of the oral mucosa, and unexplained bleeding. The fact that your symptoms resolve quickly and do not cause significant pain or lead to the formation of ulcers is reassuring.

However, it is important to consider the underlying causes of your symptoms. Occasional biting or friction can be attributed to several factors, including:
1. Dental Alignment Issues: Misaligned teeth or a malocclusion (improper bite) can lead to certain teeth coming into contact with the soft tissues of the mouth, causing irritation or minor injuries. If this is a recurring issue, it may be worth consulting with an orthodontist or dentist to assess your bite and alignment.

2. Bruxism: If you are grinding your teeth (bruxism), this can lead to wear on the teeth and irritation of the gums and soft tissues. Stress is a common trigger for bruxism, and if you are experiencing increased stress, it might be contributing to this habit. A dental professional can provide a night guard to help protect your teeth and gums from the effects of grinding.

3. Oral Hygiene: Maintaining good oral hygiene is crucial. If food particles or plaque accumulate around the molars, they can cause irritation to the surrounding tissues. Regular brushing and flossing, along with routine dental check-ups, can help prevent these issues.

4. Injury from Food: Sometimes, sharp or hard food items can cause minor injuries to the oral mucosa. If you notice that certain foods trigger these symptoms, it may be helpful to avoid them.

Regarding your concern about wasting medical resources, it's always better to err on the side of caution when it comes to health. If your symptoms persist, worsen, or if you develop new symptoms such as persistent pain, swelling, or changes in the appearance of your oral tissues, it would be prudent to seek a professional evaluation. A dentist or oral health specialist can provide a thorough examination and determine if any further investigation, such as imaging or biopsy, is necessary.

In conclusion, while your occasional biting and minor bruising are unlikely to be signs of oral cancer, they warrant attention to ensure that there are no underlying dental issues contributing to your discomfort. Regular dental visits and open communication with your healthcare provider about any changes in your oral health are key to maintaining good oral hygiene and overall health. If you have ongoing concerns, do not hesitate to consult a dental professional for peace of mind and appropriate care.
