Although I have been using this product for awhile and it has proven to be effective I am a little annoyed that I cannot buy the pen on it's own. I have looked in several drugstores and pharmacies to only find that you have to purchase the set. The only reason it bothers me is because the toothbrush sold with the set is one of the cheaper toothbrushes that can sometimes go on sale for a dollar. The set itself is not cheap and I feel like I rather just pay for the pen and buy my own toothbrush. Despite this flaw, I had been struggling with super sensitive teeth and nothing seemed to help until my dentist recommended this. It has been helping thus far and I do rotate using it with my other toothpastes.

I really like this toothbrush. It is easy to use and reaches all your teeth. I find it cleans better then other toothbrushes. I really like the built in sensitivity relief pen. It works great. I have very sensitive teeth and this pen works great. By using this sensitivity pen I don'y have to use my special sensitivity toothpaste which wears away my enamel.

This sensitivity toothbrush is really soft! You can hardly feel the bristles when you brush your teeth. The sensitivity pen works well. I have some sensitive teeth and after using both the toothbrush and pen I noticed a huge improvement. My teeth were not sensitive after using this toothbrush and pen.

I purchased this toothbrush a few days ago for a great price it was on sale at Shoppers Drug Mart I have sensitive teeth for a while now I've only used this product for 2 days it's very effective I have noticed a difference with less pain and my teeth look more brilliant I would recommend this product to anyone

Grace a Colgate-Palmolive j'ai essayer cette brosse a dents durant les 2 dernieres semaines a des fins d'évaluation alors voici mon avis. Cette brosse a dents avec stylo anti-sensibilité intégré est tout simplement merveilleuse en tout points. Elle est vraiment tres douce pour les dents et les gencives sensible ce qui rend le brossage tres facile et sans douleur. La brosse nettoie aussi tres bien dans les recoins. Pour ce qui est du stylo anti-sensibilité je suis tombée sous le charme. Tres facile a utiliser et appliquer ce gel enleve instantanément toute sensibilité. Que ce soit avec le chaud ou avec le froid, aucun probleme. Je recommande cette brosse a dents a tout le monde. Utilisé avec le dentifice et le rince -bouche Colgate Sensitive Pro-relief pour un résultat optimal contre la sensitivité.

I was really happy with this toothbrush and am going to continue to use it as my regular toothbrush. I'm not a huge fan of soft brushes in general, but lately after seeing my dentist, he said that people with sensitive teeth should definitely be using a 'soft' brush so this is perfect in that regard.

I like that the 'sensitivity' tool fits neatly into the toothbrush handle so that I'll never lose it or have to find somewhere to store it and it did seem to help when I had badly sensitive spots (which only happens rarely to me when using a sensitive toothpaste). The handle is comfortable and I was able to reach all my teeth with the smaller head.

I love that they thought to include a cheek and tongue scraper, as many toothbrushes don't and I only buy those that include them as for me it's a dealbreaker!
