Fish Scale Spines in the Mouth: Causes and Treatments - Dermatology

More Info

---

When it comes to the presence of fish spines or scales in the mouth, it can indeed be a perplexing and concerning issue. Fish spines, or more commonly referred to as fish bones, can sometimes cause discomfort or injury if they become lodged in the oral cavity or throat. However, it seems that your situation involves a different concern, specifically the development of lesions or sores in your mouth, which your dermatologist has identified as possibly related to fish scales.

Firstly, it's important to clarify that fish scales themselves are not typically harmful when they are in the mouth, but they can cause irritation or allergic reactions in some individuals. If you are experiencing sores or blisters in your mouth, it could be due to a variety of reasons, including:
1. Aphthous Ulcers (Canker Sores): These are small, painful ulcers that can appear on the inside of the mouth, including the lips, cheeks, and tongue. They are often triggered by stress, certain foods, or underlying health conditions.

2. Herpes Simplex Virus: This virus can cause cold sores or fever blisters, typically around the lips but can also affect the inside of the mouth.

3. Irritation from Fish Scales or Spines: If you have indeed come into contact with fish scales or spines, they could cause localized irritation or injury, leading to sores.

4. Allergic Reactions: Some individuals may have allergic reactions to certain types of fish or seafood, which can manifest as oral lesions.

5. Infections: Bacterial or fungal infections can also lead to sores in the mouth.

Given your description of the lesions and the concern about them being fish scales, it is advisable to monitor the situation closely. Here are some recommendations for treatment and care:

Treatment Options:
- Topical Treatments: Over-the-counter topical anesthetics like benzocaine can help relieve pain from sores. Additionally, topical corticosteroids may reduce inflammation if prescribed by a healthcare provider.

- Mouth Rinses: Saltwater rinses or antiseptic mouthwashes can help keep the area clean and promote healing.

- Avoid Irritants: Steer clear of spicy, acidic, or abrasive foods that may exacerbate the irritation.

- Hydration: Ensure you are drinking plenty of fluids to keep your mouth moist and promote healing.


When to Seek Medical Attention:
- If the sores persist for more than two weeks without improvement.

- If you develop a fever or experience significant pain.

- If you notice swelling or difficulty swallowing, which could indicate a more serious issue.


Preventive Measures:
- Good Oral Hygiene: Maintain a regular oral hygiene routine, including brushing and flossing, to prevent infections.

- Dietary Considerations: If you have a known sensitivity to fish or seafood, it may be wise to avoid these foods to prevent allergic reactions.

- Stress Management: Since stress can trigger canker sores, consider incorporating stress-reduction techniques such as mindfulness or relaxation exercises into your routine.

In conclusion, while the presence of fish scales or spines in the mouth can be concerning, it is essential to differentiate between irritation caused by these and other potential causes of oral lesions. If you continue to experience discomfort or if the lesions worsen, consulting a healthcare professional, such as a dentist or an oral specialist, would be prudent for a thorough evaluation and tailored treatment plan.
