Cleaning Between Teeth: Methods and Product Recommendations for 2026
Cleaning between your teeth is a fundamental part of a comprehensive oral hygiene routine. Conventional brushing often only reaches about 60% of tooth surfaces, leaving the interdental spaces—the areas between the teeth—inadequately cleaned. Food debris and bacteria can accumulate in these niches, leading to the formation of plaque. Consistent interdental cleaning is therefore essential for gum care and preventing cavities and gingivitis.
This article analyses the technical differences between common methods and presents a selection of products tailored to specific user needs.
Buyer's Guide: Selection Criteria for Cleaning Tools
Choosing the right tool for cleaning between your teeth depends on individual factors like tooth alignment, the presence of dental work or orthodontic appliances, and personal preferences. Two primary technologies are available: oral irrigators and interdental brushes.
Oral Irrigators (Water Flossers)
An oral irrigator, also known as a Water Flosser, cleans between the teeth using a pulsating jet of water. This flushes out food debris and loose plaque from interdental spaces while simultaneously massaging the gums.
Technical Selection Parameters:
- Nozzle Technology: Modern devices offer specialised nozzles that split the water jet (e.g., into four streams) to clean a larger area more quickly and thoroughly. A 360-degree rotating nozzle allows you to reach difficult areas.
- Cleaning Modes and Intensity Levels: Adjustable modes (e.g., a standard Clean mode and a Deep Clean mode) and multiple pressure settings allow for customisation based on individual gum sensitivity.
- Reservoir Capacity: The volume of the tank (usually specified in millilitres) determines how long the device can be used without refilling. A capacity of around 250 ml is often sufficient for a 60-second cleaning cycle.
- Power and Portability: A cordless oral irrigator with battery operation and USB charging offers maximum flexibility and is ideal for travel. Battery life is specified in days or weeks of typical use.
Interdental Brushes
Interdental brushes work on a purely mechanical basis. A fine, coated wire fitted with bristles is inserted into the space between teeth to remove plaque with a back-and-forth motion.
Technical Selection Parameters:
- ISO Size: Interdental brushes are available in various standardised sizes (ISO 0-8). The correct size is crucial to ensure the brush fills the space without damaging the gums or teeth. The corresponding Passage Hole Diameter (PHD) is often indicated on the packaging.
- Wire and Coating: The wire should be made of surgical-grade material and be plastic-coated. This coating protects sensitive surfaces, especially around implants, bridges, and braces.
- Bristles and Handle: The quality of the bristles and the ergonomics of the handle determine the effectiveness and comfort of use. Some bristles are additionally coated with substances like sodium fluoride or chlorhexidine.

Frequently Asked Questions (FAQ)
1. Is an oral irrigator more effective than interdental brushes? Both methods aim to remove plaque but use different mechanisms. An oral irrigator uses water pressure and is often easier to handle, especially with crowded teeth or braces. Interdental brushes clean mechanically and can be very thorough when the correct size is used. The choice depends on individual tooth alignment, motor skills, and personal preference.
2. How often should you clean between your teeth? Dental organisations generally recommend cleaning between your teeth daily to effectively control the build-up of plaque and food debris and to support gum care.
3. Can an oral irrigator be used on sensitive gums? Yes, many oral irrigators, like the featured Philips Sonicare oral irrigator, offer multiple intensity levels. Users can start with a low pressure setting and adjust it as needed. The water jet can also have a massaging effect on the gums.
