Rubber Dental Picks Versus Interdental Brushes: Comfort and Cleaning

A rubber or silicone-coated dental pick may feel more comfortable than a wire-core interdental brush. That preference showed up in small clinical trials, alongside similar short-term plaque and bleeding results.¹² If you are considering a switch, bring both products to your hygienist and ask whether the softer pick reaches the surfaces you need to clean.

The two-week comparison

A 2020 randomized split-mouth trial¹ included 30 people with gingivitis. After professional cleaning and a three-day washout, participants used TePe Interdental Brushes Original and TePe EasyPick on assigned sides, following instructions. Researchers measured plaque and gum bleeding at baseline and two weeks; a questionnaire assessed comfort and satisfaction.¹

Both devices improved the plaque and bleeding scores, with no detected difference between sides in how the scores changed. Participants reported greater comfort and satisfaction with the silicone-coated pick, and less pain. These findings concern those two products over two weeks. They do not establish that every rubber pick cleans as well as every brush, or that either prevents tooth loss over years.¹

A four-week study also measured preference

In a 2014 randomized crossover study² reported in 39 patients, researchers compared a Fuchs rubber interdental bristle with a TePe metal-core interdental brush. Participants used the products in randomly assigned order. Both reduced plaque after a single use and bleeding after four weeks, without a statistically significant difference between products in the reported bleeding result.²

The rubber product received better ratings for comfort, less pain during use and willingness to buy. That is useful information for someone who dislikes a wire-core brush. It remains a patient-experience finding, rather than proof of superior gum protection.²

What the review could establish

A systematic review published online in 2021 and in a 2022 journal issue included six studies with ten comparisons, searching through August 2020. Overall plaque and bleeding results did not clearly distinguish rubber-bristled cleaners from the compared devices. Participants tended to prefer the rubber products, and some studies found fewer gum abrasions.³

The reviewers rated the evidence for plaque and gingivitis reduction weak to very weak. Studies were short, used different designs and products, and involved industry participation. Many participants had limited inflammation. The reviewers specifically cautioned against extending the findings to periodontitis patients, for whom suitable evidence was lacking.³

A device that is pleasant to hold can still be unsuitable for a particular space between teeth. Ask your dental team to check cleaning access as well as comfort before you replace a recommended brush.

Make the fitting appointment specific

Dorset County Hospital advises using the interdental brush size recommended by your dentist or hygienist and avoiding force, which can damage gums. It also asks patients to report bleeding, pain and sore areas.⁴ Bring the actual packet so the team can identify the product and size.

Ask the hygienist to demonstrate it at the back teeth as well as the front. Point out exactly where the tool hurts, bends or will not enter. Request a written list of which product and size to use in each area, including any places that need another cleaning method. Ask how the team will assess whether your revised routine is controlling plaque and bleeding.

Bleeding deserves assessment

The NHS⁵ recommends daily cleaning between teeth with floss or interdental brushes, alongside brushing with fluoride toothpaste at least twice a day. It advises seeing a dentist for bleeding gums, painful swelling or bad breath. Very sore, swollen gums or loosening teeth need an urgent dental appointment.⁵ A preference for a softer tool should not postpone that assessment.

Is It My Breath? discusses the limits of interdental-cleaning evidence in Chapter 6, “Gums, Floss and Hormones,” under “The Floss Story.” The chapter also discusses choosing a tool for your tooth spaces as part of a daily-care routine.
