Below is clear, careful, and age-appropriate information about using guava leaves as a supportive home remedy for oral health.
⚠️ Important first: Dental cavities cannot be cured at home. Once a cavity forms, only a dentist can permanently treat it. Guava leaves may help reduce bacteria, soothe gums, and slow worsening, but they do not replace professional dental care.
1. Guava Leaf Mouth Rinse (Most Common & Safest Method)
Why it helps
Guava leaves contain natural compounds with antibacterial and anti-inflammatory properties. A rinse may help reduce mouth bacteria and soothe irritated gums.
What you need
-
5–10 fresh guava leaves (or 1 tablespoon dried leaves)
-
2 cups clean water
Directions
-
Wash the guava leaves thoroughly.
-
Boil the leaves in water for 10–15 minutes.
-
Let the water cool until warm (not hot).
-
Strain out the leaves.
-
Swish the liquid in your mouth for 30–60 seconds.
-
Spit it out (do not swallow).
-
Rinse your mouth with plain water afterward.
How often
-
1–2 times per day, after brushing.
Safety notes
-
Stop if you feel irritation or burning.
-
Do not replace toothpaste or brushing with this rinse.
2. Chewing Fresh Guava Leaves (Traditional Method)
Why it helps
Chewing releases natural antibacterial compounds and may help reduce plaque-causing bacteria.
What you need
-
1–2 young, tender guava leaves
Directions
-
Wash the leaves very well.
-
Chew slowly for 1–2 minutes.
-
Spit out the remains.
-
Rinse your mouth with clean water.
How often
-
Once per day, after meals.
Safety notes
-
Do not chew if the leaves taste bitter or cause discomfort.
-
Avoid if you have mouth sores or cuts.
-
Not recommended for young children.
3. Guava Leaf Paste (For Gums, Not Holes)
Why it helps
May reduce gum inflammation and bacterial growth around the tooth—not inside the cavity.
What you need
-
3–4 fresh guava leaves
-
A few drops of clean water
Directions
-
Wash and crush the leaves into a paste.
-
Apply a small amount to the gums near the affected tooth.
-
Leave on for 5 minutes.
-
Rinse your mouth thoroughly with water.
How often
-
Once daily, for a few days only.
Safety notes
-
Do not pack paste into a tooth hole.
-
Stop if irritation occurs.
