Sticky White Residue on Gums After Brushing: Causes and Solutions - Dentistry

Share to:

After brushing, there is a sticky substance between the teeth and gums?


Hello, after I brush my teeth (with toothpaste), I notice a lot of white, sticky substance on my gums about an hour later.
Rinsing my mouth doesn't remove it, and I have to use my fingers to rub it off.
What could this condition be, and should I see a dentist? Thank you.

The above situation may be due to the accumulation of dental plaque in the interproximal spaces and along the cervical areas of the teeth.
It is recommended that, in addition to brushing, you should also use dental floss to clean between the teeth.
When brushing the cervical areas near the gums, make sure to clean them thoroughly.
Additionally, drinking plenty of water can help keep the oral environment from becoming dry, which can prevent plaque from adhering to the teeth.

More Info


The presence of a sticky white residue on your gums after brushing can be concerning, and it’s understandable that you want to know what it is and how to address it. This residue could be caused by several factors, including plaque buildup, food particles, or even a reaction to the toothpaste you are using.
Plaque is a sticky, colorless film of bacteria that forms on your teeth and gums. If not removed through regular brushing and flossing, it can harden into tartar, which can lead to gum disease. The white residue you are experiencing may be an accumulation of plaque that has not been adequately removed during brushing. Additionally, if you are using a toothpaste that contains certain ingredients, such as sodium lauryl sulfate (SLS), it could contribute to a mucous-like residue on your gums, especially if you have a sensitivity to it.

Another possibility is that the white substance is related to a condition known as oral thrush, which is a fungal infection caused by an overgrowth of Candida yeast. This condition can lead to white patches in the mouth, including on the gums, and may be accompanied by discomfort or a burning sensation. If you notice other symptoms such as soreness, difficulty swallowing, or a persistent bad taste in your mouth, it would be wise to consult a healthcare professional.

To address the sticky white residue, here are some steps you can take:
1. Improve Oral Hygiene: Ensure that you are brushing your teeth at least twice a day for two minutes each time, and flossing daily. Pay special attention to the gum line, as this is where plaque tends to accumulate.

2. Choose the Right Toothpaste: If you suspect that your toothpaste may be contributing to the problem, consider switching to a toothpaste that is free from SLS or other harsh ingredients. Look for products that are specifically designed for sensitive gums.

3. Rinse Properly: After brushing, make sure to rinse your mouth thoroughly with water. You might also consider using an alcohol-free mouthwash to help reduce plaque buildup and freshen your breath.

4. Stay Hydrated: Sometimes, a dry mouth can exacerbate the feeling of residue on your gums. Drink plenty of water throughout the day to keep your mouth moist.

5. Regular Dental Visits: It is essential to see your dentist regularly for check-ups and cleanings. They can help remove tartar buildup and provide personalized advice based on your oral health.

If the sticky residue persists despite improving your oral hygiene routine, or if you experience any pain, swelling, or other unusual symptoms, it is advisable to schedule an appointment with your dentist. They can perform a thorough examination to determine the underlying cause of the issue and recommend appropriate treatment.

In summary, while the sticky white residue on your gums may be a common issue related to plaque buildup or a reaction to toothpaste, it is essential to maintain good oral hygiene and consult a dental professional if the problem continues or worsens. Your oral health is crucial, and addressing any concerns promptly can help prevent more serious issues down the line.
