It’s common to experience discomfort or swelling in your gums after flossing, especially if you’re just starting the habit or flossing too forcefully. This irritation often results from improper technique, plaque buildup, or sensitivity in neglected areas.
While it can be frustrating, swollen gums after flossing are usually temporary and can be treated effectively with the right approach. By adjusting your flossing technique, using soothing remedies, and maintaining good oral hygiene, you can reduce swelling and get your gums back to feeling healthy. Let’s take a look at the steps you can take to treat and prevent this issue.
Steps to Treat Swollen Gums After Flossing
Here’s how to address swollen gums and prevent further irritation with these simple steps:
1. Rethink Your Flossing Technique
Aggressive flossing can irritate your gums, causing them to swell. Snapping the floss between your teeth can create tiny cuts and lead to irritation. The key to effective flossing is to be gentle. Slide the floss slowly between your teeth, and once it reaches the gum line, curve it around each tooth and gently move it up and down. Avoid snapping or forcing the floss between your teeth. Proper technique will ensure your gums are cleaned without causing any irritation.
2. Switch to a Softer Floss
The floss you’re using may be the root cause of the problem. If it’s too thick or rough, it can cause unnecessary friction, leading to swollen gums. Try switching to a softer nylon or silk floss that glides more easily between your teeth. Soft, unwaxed floss is also less likely to irritate your gums. Using the right type of floss can make a big difference in reducing irritation, especially if you’re experiencing consistent swelling after flossing.
3. Use a Saltwater Rinse
A saltwater rinse is a simple and effective way to reduce swelling and soothe sore gums. Saltwater has natural antibacterial properties that help fight infection and reduce inflammation. Mix half a teaspoon of salt in a cup of warm water and rinse your mouth for 30 seconds. This technique will help reduce swelling, cleanse your gums, and remove any bacteria that might contribute to the issue. Saltwater rinses are easy to do and can be repeated several times a day for relief.
4. Apply a Cold Compress
If your swollen gums are causing pain, a cold compress can help numb the area and reduce inflammation. Apply a cold pack or wrap some ice in a cloth and gently place it outside your cheek where the swollen gums are. Hold it there for 10-15 minutes. The cold constricts the blood vessels and reduces swelling, giving you quick relief. This technique is especially helpful if your gums are tender and sore after flossing.
5. Use a Non-Alcoholic Mouthwash
Mouthwash is another useful tool for soothing swollen gums, but make sure to choose the right one. Alcohol-based mouthwashes can dry out your gums, making the swelling worse. Instead, opt for an alcohol-free mouthwash that contains fluoride or natural antibacterial ingredients. These will help kill bacteria and promote gum health without causing further irritation. Swish the mouthwash for 30 seconds after brushing and flossing to help kill bacteria and soothe inflammation.
6. Maintain Proper Oral Hygiene
Even when your gums are swollen, it’s essential to keep up with your oral hygiene routine. Continue brushing your teeth twice a day with fluoride toothpaste, but be gentle around the swollen area. Using a soft-bristled toothbrush will help avoid further irritation. Don’t skip flossing altogether, but make sure to be more gentle. Consistent, proper care will prevent plaque buildup and promote healing. Skipping your routine can make the swelling worse and lead to further gum issues.
7. See Your Dentist
If your gums stay swollen for over a few days, bleed heavily, or show signs of infection like pus or persistent pain, make an appointment immediately. Your dentist can examine your gums and determine the cause of the swelling, whether it’s from an infection, plaque buildup, or other underlying problems. Early intervention can prevent more serious conditions, so don’t hesitate to schedule an appointment if the swelling doesn’t improve after a few days.
Conclusion
Swollen gums after flossing can be uncomfortable, but with the right steps, you can treat the irritation and restore your gums to a healthy condition. Start by adjusting your flossing technique, switching to softer floss, and incorporating saltwater rinses and cold compresses into your routine.
Don’t forget to maintain good oral hygiene and use an alcohol-free mouthwash to soothe your gums. If the swelling persists, it’s crucial to see your dentist for further care.
