Colgate A1500There has been a lot of hype in dental circles about Colgate’s new ProClinical A1500 Electric toothbrush. And rightly so, this is potentially a game-changer for Colgate, expanding their market reach from low-cost battery operated electric toothbrushes to a professional grade electric toothbrush.

As part of my product review I was instructed to give Colgate ProClinical A1500 Electric Toothbrush a two-week trial to get used to the feel and functionality. Given: a) I’m a dentist; and b) I’ve been cleaning my teeth now for 30 plus years; I was skeptical that it would take me that long to master this toothbrush. But they were right.

Let me start by saying this is a serious toothbrush. The Colgate ProClinical A1500 Electric Toothbrush is different to any electric toothbrush that I have ever used. So much so, that you essentially have to re-learn how to clean your teeth with this toothbrush. The weight, the shape of the head, the multiple cleaning speeds and multiple motion sensors all add up to a very different electric toothbrush cleaning experience.

You need to be patient and learn the basics of the ProClinical A1500. If you jump into the deep end and use the advanced settings straight up, you won’t have the right technique to get the best out of the toothbrush.

The specifications:

  • The Colgate ProClinical A1500 Electric Toothbrush has three different speeds and multiple motion settings that adjust depending on where the brush is held in your mouth.
  • It packs a punch with its sonic cleaning action that delivering 32, 500 strokes per minute. Impressive. It claims to remove more plaque build-up along the gum-line compared to a standard manual brush and a leading electric toothbrush.
  • Bristles – there are a three different types that maximize the clean in the various positions you hold the toothbrush.

Impressions on first use

WOW. This is like a rocket bouncing around in your mouth. It is lightweight and powerful. It also tickles. The sonic cleaning action can also be a bit brutal on the gums on the first few uses.

With the multiple speeds and motion settings comes the need to perfect your brushing technique to really get the best out of this high-powered brush. I think the AUTO setting is a good place to start while you get used to everything, but I don’t think it delivers the best clean.

The slow-speed setting did an average job of cleaning the buccal/lingual surfaces (front and side facing surfaces of my teeth). These are the surfaces that I needed to re-clean during the trial period. However once I mastered the recommended trial AUTO setting, the more powerful OPTIMAL setting takes care of any disappointment I had and the surfaces of my teeth feel clean to the tongue touch.

The Colgate ProClinical A1500 Electric Toothbrush does a great job cleaning along the gum line when you master the 45-degree hold. If you have a problem with plaque build-up on your gum line then this is a great toothbrush for you to try. I’m also happy with how it cleans the occlusal surfaces (top surface of the bite teeth).


  • Extremely lightweight and balanced. I like the shape of the ProClinical A1500. It is sleek, slim and feather light.
  • The toothbrush head is a similar shape to a non-electric toothbrush, but smaller in size, which I really like. It also has an angled neck making it easier to reach the back teeth surfaces.
  • The bristles are a mix of tapered outer bristles, inner bristles and spiral bristles. The tapered and fine bristles tickle on the first use.
  • It comes with enough battery power to clean your teeth as soon as you get home, this is a nice touch. You then plug-in the toothbrush for 16 hours to completely charge the battery.


  • It doesn’t work like a standard electric toothbrush. You have to re-learn how to clean your teeth. But, when you master the angles and speeds you will clean your teeth more effectively than before.
  • It is noisy. Super-sonic noisy. Not at all relaxing. This is my biggest gripe but I’m sure they will reduce this as they refine the product.
  • If you are tired and not concentrating on how you are holding the toothbrush it is easy to miss areas of plaque.
