toothbrush heads sensitive

Indicator bristles are dyed (commonly blue) and gradually fade to a lighter shade or white with use. When the color has noticeably faded—typically after about three months—it provides a visual cue that it’s time to replace the sensitive brush head.

Product details and dental professionals generally recommend replacing a sensitive brush head about every three months.

Sensitive replacement heads typically use plastic bodies with soft nylon bristles. Some listings specify DuPont nylon, food‑grade materials, and a soft silicone backing on certain models.

Some sensitive heads include clear protective covers for hygienic storage and travel. Certain product listings also show recyclable, paper‑based outer packaging.

Common pack sizes include 3‑count and 4‑count multipacks, with larger value packs such as 8 heads available in some listings.

Many sensitive‑head listings specify 'Suggested Age: 8 Years and Up.' A few listings show other ages (for example 3 or 10 years), so age recommendations are not consistent across all products.
