What are Oral-B Sensi UltraThin Replacement Electric Toothbrush Heads?

Oral-B Sensi Ultrathin Toothbrush Heads are a replacement head for Oral-B toothbrushes that removes 100% plague and reduces inflammation in the gums by 100% when compared to manual toothbrushes.


How do these toothbrush heads work?

They work by having thin bristles which are ideal for sensitive gums, alongside more regular-sized bristles that help to remove plaque. The round heads contour around the teeth to provide a better clean, in comparison to manual toothbrushes.


 Who are these Oral-B Sensi UltraThin heads suitable for?

They are suitable for anyone using an Oral-B electric toothbrush that is compatible with these heads. Those are most of the Oral-B range, except for the sonic range. These toothbrushes should not be used by anyone aged under 3 years old.


How often should I be changing my toothbrush head?

It is recommended that you change your toothbrush head on your electric toothbrush every 3-4 months. This is because over time they will fade when in use and the bristles will no longer work as effectively.


Why should I choose Sensi UltraThin over other Oral-B toothbrush heads?

Sensi Ultrathin heads are ideal for those with sensitive gums that may find other Oral-B toothbrush heads to be uncomfortable. The petal-shaped bristles are designed to be kind to gums while helping to fight against gingivitis and reducing inflammation. This all means that using these toothbrush heads will improve gum health.
