After teeth cleaning, the gums may become swollen?


I was diagnosed with mild periodontal disease at a dental clinic a month ago.
Yesterday afternoon, I returned for a dental cleaning treatment.
That evening, while brushing my teeth, I noticed that my gums were painful.
Today, although my gums are not very painful while brushing, I have noticed swelling behind my front teeth, which does not hurt when pressed.

Hello: If you are experiencing severe gum swelling and pain, it is advisable to return to the clinic for a physician to prescribe simple anti-inflammatory and analgesic medications to help you through the acute inflammatory phase.

Swollen gums after a dental cleaning can be concerning, especially if you have a history of periodontal disease. It’s important to understand the potential causes and how to manage them effectively.

Causes of Swollen Gums After Teeth Cleaning:
1. Irritation from Cleaning Tools: During a dental cleaning, the hygienist uses various instruments to remove plaque and tartar. This process can sometimes irritate the gums, especially if there is existing inflammation from periodontal disease. The mechanical action of scraping can lead to temporary swelling.

2. Existing Gum Disease: If you have been diagnosed with mild periodontal disease, your gums may already be inflamed. The cleaning process can exacerbate this condition temporarily, leading to swelling and discomfort.

3. Infection: Although less common, if there is an underlying infection in the gums, the cleaning can sometimes trigger an inflammatory response, leading to swelling. This is particularly true if there are pockets of bacteria that were disturbed during the cleaning.

4. Allergic Reaction: In rare cases, some patients may have an allergic reaction to the materials used during the cleaning, such as certain types of toothpaste or rinses.

5. Post-Cleaning Sensitivity: After a cleaning, it’s not unusual for some patients to experience increased sensitivity in their gums and teeth. This can lead to a feeling of discomfort or swelling.

Solutions and Management:
1. Good Oral Hygiene Practices: Continue to maintain good oral hygiene by brushing twice a day with a soft-bristled toothbrush and using fluoride toothpaste. Be gentle around the swollen areas to avoid further irritation.

2. Salt Water Rinse: Rinsing with warm salt water can help reduce inflammation and promote healing. Mix about half a teaspoon of salt in a glass of warm water and rinse your mouth gently.

3. Avoid Irritants: Stay away from irritants such as tobacco, alcohol, and spicy foods that can aggravate the gums.
4. Use an Antimicrobial Mouthwash: An antimicrobial mouthwash can help reduce bacteria in the mouth and promote gum health. However, avoid using mouthwash immediately after brushing, as it can wash away the fluoride from your toothpaste.

5. Cold Compress: If there is swelling, applying a cold compress to the outside of your mouth can help reduce inflammation and numb the area.

6. Follow-Up with Your Dentist: If the swelling persists for more than a few days or worsens, it’s essential to follow up with your dentist. They may need to assess for any underlying issues, such as infection or deeper periodontal problems.

7. Professional Cleaning Schedule: Ensure you are on a regular cleaning schedule, as recommended by your dentist. Regular cleanings can help manage and prevent periodontal disease.

8. Consider Periodontal Treatment: If you have ongoing issues with gum disease, your dentist may recommend more intensive periodontal treatments, such as scaling and root planing, to help manage the condition.

In summary, while swollen gums after a dental cleaning can be a common occurrence, especially for those with a history of gum disease, it’s crucial to monitor the situation. Maintaining good oral hygiene, using home remedies like saltwater rinses, and following up with your dentist if symptoms persist will help ensure your gums heal properly and prevent further complications.
