A sonic toothbrush that upgrades your routine

What reviewers say

Questions and answers

Is the Oasismile sonic toothbrush worth it?

At $14.99 at Walmart as of November 2, 2026, it is a low-cost way to try sonic brushing. You get five modes, a timer and six brush heads, which is more than most brushes at this price.

How long does the battery last on a charge?

Oasismile claims up to 90 days per charge. Buyers report multiweek runtime with twice-daily brushing, so expect less than the claim with heavy use of high modes.

Does it come with replacement brush heads?

Yes. The box includes the brush handle and six replacement brush heads. No charger details or travel case are listed.

Is it good for sensitive gums or braces?

It has dedicated sensitive and braces modes, and buyers say the lower settings suit sensitive use. The vibration is strong on higher modes, so start low if your gums are tender.

How does it compare with a rotating brush like Oral-B?

This is a sonic brush that vibrates the bristles rather than spinning a round head. Sonic brushes are generally quieter and gentler in feel, while rotating brushes are often praised for a scrubbing clean.

When is the cheapest time to buy it?

Its lowest recorded daily price is $14.99 at Walmart on November 2, 2026, and it has not gone lower since. There is no cheaper window to wait for based on that history.
