No reliable evidence currently shows that avocado seed powder can rebuild tooth enamel or reverse an established cavity.
Once a cavity has created a physical hole in the tooth, simply placing a plant powder over the area cannot restore the lost tooth structure.
Depending on how advanced the decay is, professional treatment may involve fluoride treatment, a dental filling, or other procedures.
This is why natural remedies should not delay a dental examination.
Why You Should Be Careful With Home Remedies
Applying homemade powders directly to teeth may seem harmless, but there are several potential concerns.
A coarse powder could irritate the gums or sensitive oral tissues. Homemade preparations may also contain contaminants if the seed is not properly cleaned, dried, stored, or processed.
