You brush. You floss (most nights, anyway). And your dentist still finds something to talk about at every visit. If that's you, there's a good chance you'll find BioGaia's oral probiotic interesting.

BioGaia Prodentis is a lozenge that adds friendly bacteria to your mouth. It's the top oral probiotic on Amazon, and the company says it's the oral probiotic brand dental hygienists recommend most.

Your mouth has a microbiome too

We hear a lot about gut bacteria. Your mouth has its own community as well, a mix of helpful and less helpful bacteria. BioGaia's point is simple. Brushing and flossing clear away plaque, but they don't add good bacteria back. A probiotic can.

The company says having enough good bacteria in the mouth helps defend against common dental problems and keeps your mouth fresh. That's the whole idea behind this product.

Two strains with a research history

BioGaia Prodentis uses two strains of Lactobacillus reuteri:

• L. reuteri ATCC PTA 5289

• L. reuteri DSM 17938

BioGaia is a Swedish company that's been working with L. reuteri for a long time. It says it has more than 30 years of probiotic research and over 70 clinical studies behind its brand. Few oral probiotics can point to that kind of track record, and it's a big reason dental professionals are comfortable suggesting it.

What it's designed to do

According to BioGaia, Prodentis:

• promotes healthy gums and teeth

• helps maintain a healthy balance of bacteria in the mouth

• helps fight bad breath

The fresh-breath part is a nice bonus. A lot of people notice their mouth simply feels cleaner.

The L. reuteri DSM 17938 strain may sound familiar if you've ever shopped for baby probiotic drops. It's the same strain BioGaia uses in its well-known infant drops, which gives you a sense of how much confidence the company has in it. In BioGaia Prodentis, it's paired with a second strain chosen specifically for the mouth.

How you use it

This might be the easiest supplement routine I know of. Once a day, ideally after you brush your teeth, let one lozenge slowly melt in your mouth. Don't chew it. Letting it dissolve gives the bacteria time to settle in where they're needed.

I like doing it at night. Brush, floss, lozenge, bed. It becomes part of the routine within a week. Try not to eat or drink for a little while afterward, so the lozenge has a quiet window to do its thing. If mornings suit you better, after brushing at breakfast works fine too.

The flavor is natural peppermint and menthol, so it tastes like a breath mint. It's sweetened with isomalt and xylitol, and xylitol is a sweetener dentists tend to like anyway. One box holds 30 lozenges, which is a month's supply.

Clean and simple

The lozenges are free from alcohol and artificial colors, and BioGaia says the formula is certified microbiome friendly. Unlike many mouthwashes, there's no burn and nothing to spit out.

Who'll get the most from it

• people who want to go a step beyond brushing and flossing

• anyone whose dentist or hygienist has mentioned gum health

• people bothered by morning breath

• those who'd rather not use strong alcohol mouthwashes every day

A couple of friendly notes

Keep the lozenges well away from dogs. They contain xylitol, which is very dangerous for dogs even in small amounts. Too much xylitol or isomalt can upset some people's stomachs, so stick to one a day. If you have bleeding gums, a loose tooth, or tooth pain, see your dentist, since those need a proper look. And keep up your regular cleanings, because this is meant to support your routine, not replace it.

Your smile works hard for you. If you'd like an easy, pleasant way to give it a little extra care, BioGaia Prodentis is a lovely addition to your bedtime routine.
