How to Brush Wisdom Teeth Properly – A Complete Guide
Wisdom teeth can be tricky to clean, and if not brushed properly, they can cause decay, gum infections, and discomfort. Many people struggle with reaching the back of their mouth, leading to plaque build-up and potential problems.
In this guide, we’ll explain how to brush wisdom teeth effectively, why it’s important, and the best ways to keep your oral health in top condition.

Why Is It Hard to Brush Wisdom Teeth?
Wisdom teeth are the last molars to emerge, usually between late teens and early twenties. Because they sit at the very back of the mouth, they can be hard to reach, making it difficult to clean them thoroughly. Poor cleaning can lead to:
- Plaque and tartar build-up
- Gum inflammation (pericoronitis)
- Tooth decay and cavities
- Bad breath (halitosis)
If you have wisdom teeth, it’s essential to clean them properly to avoid these issues.
How to Brush Wisdom Teeth Correctly
Since wisdom teeth are often partially covered by gum tissue or positioned awkwardly, you need a careful approach when brushing. Here’s the best way to do it:
- Choose the Right Toothbrush
A small-headed, soft-bristled toothbrush is best for reaching wisdom teeth. An electric toothbrush with a rotating head can also make cleaning easier.
- Use the Right Brushing Technique
- Hold the toothbrush at a 45-degree angle to your gums.
- Use gentle, circular motions to clean all surfaces.
- Pay extra attention to the gum line to prevent bacteria build-up.
- Be Gentle but Thorough
Aggressive brushing can cause gum irritation, especially if your wisdom teeth are still erupting. Take your time and ensure you’re reaching all areas.
- Use Interdental Brushes or Floss
Flossing is just as important as brushing. If regular floss is difficult, try:
✔ Interdental brushes – Perfect for cleaning between teeth.
✔ Floss picks – Easier to manoeuvre at the back of the mouth.
- Consider a Mouthwash
An antibacterial mouthwash can help remove bacteria from hard-to-reach areas and reduce inflammation. Look for a mouthwash containing fluoride for added protection.
Brushing Wisdom Teeth with Braces or Crowding
If you have braces or crowded teeth, brushing wisdom teeth can be even harder. Here’s what you can do:
- Use a single-tufted toothbrush to reach behind the braces.
- Try orthodontic floss or a water flosser for better cleaning.
- Rinse with a fluoride mouthwash to strengthen enamel.
If your wisdom teeth are causing discomfort due to lack of space, your dentist might recommend extraction.
What If Your Wisdom Teeth Are Partially Erupted?
Sometimes, wisdom teeth only partially break through the gums, creating a flap where food and bacteria can get trapped. If this happens:
- Gently clean under the gum flap using a soft-bristled brush.
- Use warm salt water rinses to reduce swelling and discomfort.
- If pain persists, visit your dentist to check for infection or impaction.
Signs Your Wisdom Teeth Might Need Removal
Even with excellent brushing habits, some wisdom teeth cause ongoing problems due to their position. Your dentist may recommend removal if you experience:
- Persistent pain or swelling
- Repeated gum infections
- Difficulty chewing or biting
- Crowding of other teeth
If you’re unsure whether your wisdom teeth need extraction, book an appointment for a professional assessment.
