Tongue Irritation with Fixed Dental Bridges: Causes and Solutions

The tongue repeatedly rubs against the fixed dental bridge?

Hello Doctor: I had a missing left lower molar for many years and recently had a dental bridge made using my canine tooth (a total of three crowns).
However, since I started wearing the temporary crown and then the ceramic crown, my tongue has been constantly rubbing against those three fixed prostheses.
In addition to some redness and swelling (about 0.3 cm) in small spots, I also feel a persistent tingling and pain.
When I returned to my dentist, he said that it was due to the long absence of the tooth, and my tongue would eventually get used to it and find its normal position, so I wouldn't experience the redness, swelling, or tingling anymore.
Is it really true that the long absence of the tooth is causing this issue, or could it be that the shape of the prosthesis is too prominent and not suitable for me, requiring my dentist to modify the prosthesis?

Due to the prolonged absence of teeth, once dentures are placed to fill the gaps, the tongue may initially feel uncomfortable and restricted in movement.
However, as long as there is no inflammation in the gums after the placement, the patient will gradually adapt over time.

More Info

Understanding tongue irritation with fixed dental bridges can be quite complex, as it involves various factors related to dental anatomy, the design of the dental prosthesis, and individual patient responses. Based on your description, it seems that you are experiencing discomfort and irritation on your tongue due to the presence of a fixed dental bridge. This situation can arise from several causes, and it is essential to consider each one to determine the best course of action.

Causes of Tongue Irritation
1. Prosthesis Design and Fit: One of the primary reasons for tongue irritation could be the design and fit of the dental bridge. If the bridge is too bulky or has sharp edges, it can cause friction against the tongue, leading to irritation, redness, and even small ulcers. The contours of the bridge should ideally mimic the natural anatomy of the teeth and gums to minimize any discomfort.

2. Adjustment Period: After receiving a dental bridge, there is often an adjustment period where the tongue and oral tissues need to adapt to the new prosthesis. This is especially true if you have had a gap in your dentition for an extended period. Your tongue may have developed a habit of resting in a different position, and the new bridge could disrupt that, causing irritation. However, if the irritation persists beyond a reasonable adjustment period, it may indicate a need for further evaluation.

3. Underlying Oral Health Issues: If there are pre-existing oral health issues, such as gum disease or inflammation, these can exacerbate the discomfort experienced with a new dental bridge. The presence of inflammation can make the tissues more sensitive and reactive to the new prosthesis.

4. Material Sensitivity: Some patients may have sensitivities or allergies to the materials used in dental prosthetics. If the bridge contains metals or other materials that your body reacts to, this could lead to localized irritation.

5. Poor Oral Hygiene: Inadequate oral hygiene can lead to plaque buildup around the dental bridge, which can irritate the surrounding tissues and lead to inflammation. This can also contribute to a feeling of discomfort or pain.

Solutions and Recommendations
1. Consult Your Dentist: The first step should always be to communicate your concerns with your dentist. They can assess the fit and design of the bridge and make necessary adjustments. If the bridge is too bulky or has sharp edges, your dentist can smooth these areas or modify the shape to reduce irritation.

2. Oral Hygiene Practices: Ensure that you maintain excellent oral hygiene, especially around the dental bridge. Use a soft-bristled toothbrush and consider using an antimicrobial mouthwash to help reduce inflammation and irritation.

3. Tongue Care: Be mindful of your tongue's position and try to avoid excessive contact with the bridge. If necessary, you can use a tongue scraper to keep your tongue clean and reduce irritation.

4. Follow-Up Appointments: Schedule follow-up appointments with your dentist to monitor the situation. If the irritation does not improve or worsens, further investigation may be warranted, including checking for underlying issues such as gum disease or material sensitivity.

5. Consider a Second Opinion: If you feel that your concerns are not being adequately addressed, seeking a second opinion from another dental professional may provide additional insights and solutions.

In summary, while it is possible that the irritation is due to the adjustment period after having a gap in your dentition, it is also crucial to evaluate the fit and design of the dental bridge. Persistent discomfort should not be ignored, and appropriate adjustments or interventions should be made to ensure your oral health and comfort.
