Excessive Saliva After Tooth Extraction: Causes and Solutions - Dentistry

After tooth extraction, there may be persistent drooling?


Hello Doctor,
I would like to ask for your advice.
Several years ago, I had all four of my upper and lower right molars extracted, as well as my lower left molar, and I did not get dentures due to financial constraints.
Over the past few years, I have noticed an increase in saliva production; my mouth corners are often wet, and I have to constantly swallow saliva, or else it will spill out.
Additionally, the gaps between my remaining healthy teeth have widened.

Is it possible to use orthodontic treatment to move my wisdom teeth forward (the wisdom teeth are intact, but I can't clean them properly, and they sometimes feel a bit sensitive)? Are there any other options available?
Thank you very much for your time and assistance!

If you feel soreness in your wisdom teeth, you should see a dentist to check for cavities.
Missing teeth can cause misalignment of your bite and increase the gaps between your teeth.
Given your situation, orthodontic treatment may be challenging.
The simplest and most cost-effective solution is to get a removable denture to maintain the integrity of your dental arch.
As for excessive saliva, it is not directly related to missing teeth; everyone unconsciously swallows saliva at various times.
If the situation is severe, consult an internist to check for any other underlying issues.

Excessive saliva production after tooth extraction can be a perplexing issue for many patients. It is understandable to feel concerned about the increased salivation, especially after undergoing significant dental procedures like tooth extractions. Let’s delve into the potential causes of this condition and explore possible solutions.

Causes of Excessive Saliva Production:
1. Post-Operative Healing: After tooth extractions, the body initiates a healing process that can sometimes lead to increased saliva production. This is a natural response as the body works to heal the extraction site and maintain oral hygiene.

2. Changes in Oral Anatomy: The removal of teeth, especially molars, can alter the oral cavity's structure. This change may affect how saliva is distributed and drained, leading to a sensation of excess saliva.

3. Nerve Response: The extraction process can irritate the nerves in the mouth, which may trigger an increase in saliva production. This is particularly true if the extraction was complicated or involved the removal of impacted teeth.

4. Infection or Inflammation: If there is an infection or inflammation at the extraction site, the body may produce more saliva as a defense mechanism. Signs of infection can include swelling, pain, or a foul taste in the mouth.

5. Underlying Medical Conditions: Conditions such as gastroesophageal reflux disease (GERD), allergies, or even certain medications can lead to increased salivation. If you have any underlying health issues, it may be worth discussing them with your healthcare provider.

Solutions to Manage Excessive Saliva:
1. Consult Your Dentist: The first step is to return to your dentist for a thorough examination. They can assess whether the increased salivation is a result of the extraction or if there are other underlying issues that need to be addressed.

2. Maintain Oral Hygiene: Keeping your mouth clean is crucial, especially after extractions. Use a gentle mouthwash to help reduce the risk of infection and promote healing. However, avoid vigorous rinsing that could disturb the healing tissue.

3. Stay Hydrated: While it may seem counterintuitive, staying hydrated can help regulate saliva production. Drinking water can also help wash away excess saliva and keep your mouth feeling fresh.

4. Dietary Adjustments: Avoiding spicy, acidic, or overly sweet foods can help reduce saliva stimulation. Instead, opt for bland foods that are easier to manage.

5. Saliva-Reducing Medications: In some cases, your dentist may prescribe medications that can help reduce saliva production. These medications are typically anticholinergic agents that inhibit saliva secretion.

6. Orthodontic Consultation: If you are considering moving your wisdom teeth forward or addressing the spacing issues in your mouth, consulting with an orthodontist may be beneficial. They can evaluate your dental structure and recommend appropriate treatments, such as braces or aligners, to help realign your teeth.

7. Behavioral Techniques: Some patients find that practicing swallowing techniques or using oral appliances can help manage excessive saliva. These methods can help train your body to better control saliva production.

In conclusion, excessive saliva production after tooth extraction can stem from various factors, including the healing process, changes in oral anatomy, and nerve responses. It is essential to consult with your dentist to determine the underlying cause and explore appropriate solutions. Maintaining good oral hygiene, making dietary adjustments, and considering orthodontic options can all contribute to managing this condition effectively. Remember, open communication with your dental care provider is key to addressing any concerns you may have.
