Flossing and interdental cleaning remove plaque from the spaces between teeth that a toothbrush cannot reach, and choosing the right tool makes a meaningful difference to daily oral hygiene. Interdental brushes are available in a graduated range of sizes - from the finest ISO 0 and ISO 1 brushes suited to tighter gaps, through to wider ISO 4 and ISO 5 brushes for broader spaces or around orthodontic brackets. Most adults need more than one size to cover different areas of the mouth, and selecting the correct fit is key: a brush that passes through a gap too easily will not remove plaque effectively, while one that is forced through can cause gum irritation. Traditional floss remains well suited to very tight contacts and to cleaning beneath the gumline, and using both alongside regular brushing supports thorough interdental care. The range at Ronaghan's Pharmacy covers waxed and unwaxed floss, floss picks for easier single-handed use, interdental brushes in multiple sizes from brands commonly stocked across Irish pharmacies, and tongue cleaners as part of a broader oral hygiene routine. Products are available to buy online with delivery to addresses across Ireland, or in store at Ronaghan's Pharmacy. If you are unsure which interdental brush size is appropriate for your teeth or gums, speak to your pharmacist or dental professional for guidance. Always read the product label or patient information leaflet before use.Finish your oral care routine with a daily rinse from the mouthwash range.
