When people think of guava, they usually picture the sweet tropical fruit. But few realize that the leaves of the guava tree are just as powerful when it comes to oral health. Rich in antibacterial, anti-inflammatory, and antioxidant compounds, guava leaves have been used in traditional medicine for centuries to relieve toothaches, freshen breath, and support healthy gums.

While they are not a replacement for professional dental care, guava leaves can be a natural, simple, and cost-effective way to keep your teeth and gums in better condition at home. Here are the top 3 ways to use guava leaves for teeth health:
1. Chewing Fresh Guava Leaves
The simplest method is also the oldest: chewing fresh guava leaves.
- Pick two to three clean, tender guava leaves.
- Wash them thoroughly under running water.
- Chew them slowly for a few minutes, letting the juice mix with your saliva.
How it works:
The natural compounds in guava leaves, such as flavonoids and tannins, fight bacteria that cause cavities, freshen breath, and reduce gum inflammation. Chewing also releases mild analgesic (pain-relieving) effects, making it a traditional remedy for toothache.
2. Homemade Guava Leaf Mouthwash
For those who prefer not to chew raw leaves, a guava leaf rinse is easy to prepare.
- Take a handful of guava leaves (about 5–7 leaves).
- Boil them in one cup of water for 10 minutes.
- Strain and let the liquid cool to lukewarm.
- Use it as a mouthwash once or twice a day.
How it works:
This natural rinse acts as an antimicrobial solution, helping to reduce plaque buildup, kill odor-causing bacteria, and soothe swollen gums. It’s gentle and safe enough for daily use, and unlike chemical mouthwashes, it won’t disrupt the balance of your oral microbiome.

3. Guava Leaf Paste with Salt
Another traditional method is making a guava leaf paste that can be applied directly to the teeth and gums.
- Crush a few fresh guava leaves into a fine paste using a mortar and pestle (or blend them with a little water).
- Add a small pinch of salt and mix well.
- Apply the paste to the affected tooth or gently rub it onto your gums with a clean finger.
- Leave it for 5 minutes, then rinse with warm water.
How it works:
This method combines the antibacterial power of guava leaves with the natural cleansing effect of salt. It may help reduce mild gum infections, ease sensitivity, and prevent bacteria from worsening early signs of tooth decay.
Guava leaves are more than just a byproduct of the fruit tree — they are a valuable natural ally for oral health. Whether you chew them, use them as a rinse, or apply them as a paste, they can help fight bacteria, reduce inflammation, and soothe discomfort.
