Interdental Brushes

A toothbrush cannot reach every surface, so cleaning between the teeth is part of a complete daily routine. This range of interdental brushes is built around TePe brushes in several colour-coded sizes, alongside the TePe Interspace soft brush, Oral-B Essential Floss Mint and Wisdom Clean Between flossers.

Interdental brushes come in different widths because the gaps between teeth vary. TePe sizes in this range include Pink Size 0, the 0.45mm brush, Red Size 2, Green 0.8mm, Yellow Size 4 and the purple Coarse 1.1mm. The brush should fit snugly without forcing, and many people need two or more sizes for different parts of the mouth. If you are unsure, your dentist or hygienist can tell you which sizes to use. Floss and flossers suit tight gaps where a brush will not pass, and the TePe Interspace has a small tufted head for reaching around braces, crowns and the back teeth. Some gentle bleeding is common when you first start, but if it continues, see your dentist.

Every product here is stocked at Leahy's Pharmacy, a family-run Irish pharmacy in Tralee, Co. Kerry, and our pharmacists are happy to help you find the right size or format. Pair your interdental routine with a rinse from our mouthwash range.

Frequently Asked Questions

How do I choose the right size of TePe interdental brush? +
TePe brushes are colour-coded by size, from small sizes such as Pink Size 0 to wider ones such as the purple Coarse 1.1mm. The right brush slides into the gap with gentle resistance and without forcing. Many people need more than one size for different areas. Your dentist or hygienist can check your gaps and tell you which colours to use.
Are interdental brushes better than floss? +
They suit different gaps. Interdental brushes, such as the TePe range, fit wider spaces and are easy to handle, while floss, such as Oral-B Essential Floss Mint, and flossers like Wisdom Clean Between reach tight contacts where a brush will not pass. Many people use both. Your dentist or hygienist can advise which combination works for your teeth.
How often should I replace an interdental brush? +
A brush can usually be rinsed and reused until the bristles start to splay or the wire bends, which is often after about a week of daily use. Replace it sooner if it no longer slides in easily or the bristles look worn. Rinse it under water after each use and let it dry in the open air.
What is the TePe Interspace used for? +
The TePe Interspace is a single-tuft brush with a small, soft head on a long handle. It is useful for cleaning around braces, crowns, implants, gaps where a tooth is missing and the backs of the last teeth, where a standard toothbrush can be hard to angle. Use it alongside your usual toothbrush and interdental brushes as part of daily care.
