Hello, Some various shaped tissue attachments with symmetry may be your normal anatomy. Do you think there was any trauma to your right side such as biting your tongue or eating crusty bread? There are frenum attachments that secure your tongue in place. There should be an obvious center one under your tongue to compare with the areas you are concerned about. Symmetry is a good sign that this may not be a condition to be alarmed about. Monitor the area and see your dentist for further evaluation. Other conditions could include inflamed, calcified or blocked saliva ducts or blood vessels. An ulcerated area appearing could indicate a viral condition. Rule out an allergic reaction due to food, medication or habits. Consider a change in products used that may trigger a reaction. Rinse with warm salt water and take some anti-inflammatiey medication such as acetaminophen or ibuprofen. Avoid irritants such as spicy food, acidic drinks and food, smoking and alcohol. Keep well hydrated. Maintain good oral hygiene. Keep a proper diet and balanced vitamins. Provide additional details and I will be glad to comment further. Your medical and dental history would be helpful to know. Thank you for your inquiry.
