Your Daily Oral Care Routine: What Dentists and the Research Recommend

Last reviewed: October 2026

Most of what keeps your mouth healthy happens at home, in a few minutes a day. It is also easy to overcomplicate. Electric or manual? String floss or a water flosser? Is tongue scraping worth it? We went through the guidance from the American Dental Association (ADA), the CDC and the UK's National Health Service (NHS), along with large research reviews, including several from Cochrane, to put together a simple daily routine and an honest look at what the evidence does and doesn't show.

Why a daily routine matters

Gum disease is far more common than most people realize. According to the CDC, about 42% of U.S. adults aged 30 and older have periodontitis, a serious form of gum disease, and about 8% have a severe form [1]. The good news is that its early stage, gingivitis, is preventable and reversible with good oral hygiene. The CDC specifically points to brushing twice a day and flossing daily [1]. The basics are the basics for a reason.

Step 1: Brush twice a day, for two minutes

The ADA recommends brushing twice a day with a soft-bristled toothbrush and a fluoride toothpaste [3]. The NHS adds the timing: about two minutes each time, with one of those sessions being the last thing you do before bed [4].

How to brush, according to the ADA [3]:

  • Hold the brush at a 45-degree angle to your gums.
  • Move it gently back and forth in short, tooth-wide strokes. Scrubbing harder doesn't clean better.
  • Brush the outer, inner and chewing surfaces of every tooth.
  • For the inside of your front teeth, tilt the brush upright and use several up-and-down strokes.

Spit, don't rinse. After brushing, the NHS recommends spitting out the extra toothpaste rather than rinsing with water, because rinsing washes away the fluoride left on your teeth [4]. It's one of the easiest changes you can make.

Replace your brush every three to four months, or sooner if the bristles look frayed [3]. If you use an electric toothbrush, apply the same rule to the brush head. Keeping a pack of replacement heads on hand makes the swap easy to remember.

Manual or electric?

Both work. The NHS says it doesn't matter which type you use as long as you brush thoroughly, though some people find an electric brush makes that easier [4].

The research does lean slightly toward powered brushes. A Cochrane review of 56 trials with more than 5,000 participants found that powered toothbrushes reduced plaque by 11% after one to three months of use and by 21% after three months, compared with manual brushing. Gingivitis was reduced by 6% and 11% over the same periods [5]. The reviewers rated the evidence as moderate quality and noted that how much these differences matter clinically is still unclear [5].

Bottom line: a manual brush used well is better than an electric brush used badly. But if an electric brush helps you brush more thoroughly, it's a reasonable upgrade. If you're considering one, see our Sonic Electric Toothbrush Gift Set.

Step 2: Clean between your teeth once a day

Toothbrush bristles don't fully reach the tight spaces between your teeth, which is why the ADA recommends cleaning between them once a day [3] and the CDC recommends flossing alongside brushing [2].

What the research says. A 2019 Cochrane review of 35 studies involving 3,929 adults found that using floss or interdental brushes in addition to toothbrushing may reduce gingivitis or plaque compared with brushing alone, and that interdental brushes may be more effective than floss [6]. The reviewers were candid that the evidence is low to very low certainty, and that the size of the effect may not always be clinically important [6]. Even so, both the ADA and the CDC still recommend it as part of a daily routine.

Choosing a tool. The best one is the one you'll actually use every day:

  • String floss or floss picks: the classic option. Picks are easier to handle one-handed. Our Pop-Up Dental Floss Dispenser keeps them within reach on the bathroom counter.
  • Interdental brushes: small brushes that slide between teeth. The NHS suggests them especially if you have gaps between your teeth [4].
  • Water flossers: handheld devices that spray steady pulses of water. The ADA describes them as an option for people who have trouble flossing by hand, and for people with braces or bridges that make flossing difficult [7]. Research on water flossers is more limited than for floss [6], so think of one as a way to make daily cleaning easier rather than a shortcut. We carry a High-Pressure Cordless Water Flosser and a compact Portable Electric Water Flosser.

Tip: the NHS suggests flossing before you brush [4].

Step 3 (optional): Clean your tongue

Tongue scraping has become popular, so here is the honest version.

A 2010 systematic review pulled together seven small experiments on tongue cleaning. In all of them, cleaning the tongue with a scraper or tongue brush, in addition to brushing your teeth, reduced breath odor and tongue coating. The authors also concluded, though, that there isn't enough data to show it helps with chronic bad breath (halitosis) [8]. The ADA's position is that there's no evidence tongue cleaning prevents bad breath, because the bacteria grow back quickly, and that it comes down to personal preference rather than being a necessary step [9].

In short: tongue scraping is a short-term freshness step, not a cure. Plenty of people like how their mouth feels afterward. If that's you, the ADA describes the technique as starting at the back of the tongue and pulling the scraper forward [9]. Be gentle, and rinse the scraper after each pass. A simple stainless steel tongue scraper is easy to clean and lasts. If bad breath is persistent, it's worth talking to your dentist, because it can have causes a scraper won't fix.

Step 4: Everyday habits that support your routine

Brushing and cleaning between your teeth do the heavy lifting, but the CDC also recommends [2]:

  • Drinking fluoridated tap water.
  • Avoiding food and drinks with added sugar as much as possible.
  • Not using tobacco products.
  • Preventing dry mouth by drinking plenty of water or chewing sugarless gum.

If you use mouthwash, the NHS suggests using it at a different time of day from brushing, such as after lunch, so it doesn't wash away the fluoride from your toothpaste [4].

Step 5: See your dentist

The CDC recommends visiting your dentist at least once a year [2], or as often as your dentist advises. Regular checkups catch problems early, while they're easier to deal with, and a professional cleaning removes the hardened buildup that brushing at home can't.

A note on whitening

Whitening is cosmetic. It changes how your teeth look, not how healthy they are. According to the ADA, the most common side effects of whitening are temporary tooth sensitivity and gum irritation, and only natural teeth whiten, so crowns, fillings and other tooth-colored restorations won't change color [10]. The ADA encourages talking with your dentist before whitening to make sure it's right for you [10]. If you go ahead, follow the product directions closely. Our Teeth Whitening Strips are designed for everyday surface stains from coffee, tea and wine.
