One wrote: "The whitening strips are amazing! They are only strips I have found that don’t cause sensitive teeth but still make your teeth noticeably whiter even after the first use. I have been using them for two weeks now and have started to get comments about how much whiter my teeth look.

"My tip would be to make sure your teeth are really dry first. I use the mouth opener that comes in the box and then dry my teeth with cotton wool. The strips stick like a dream and I can even talk and go about my normal business whilst they are on without really noticing. Fab product!"

A second penned: "I am thrilled with the results from these teeth whitening strips: they are super easy to use, with absolutely no fuss or discomfort. After using them for just a few rounds, my teeth are noticeably brighter, and it has given me a major confidence boost!

"Plus they don't break the bank, which is always a win. However, the only thing I would say is that sometimes I found that the strips slid a little bit. Overall, these strips are a game changer for me, and I would highly recommend to all."

A third added: "I have really sensitive teeth so it’s been great to have a product that doesn’t irritate them. They’re easy to use, and don’t feel harsh. For the price as well they’re great, I would recommend them to anyone who needs them. I drink a lot of coffee so I like to use these just to make sure I’m not staining my teeth."

Some shoppers have said that they find the mouth guard to be too large. One said: "I quickly ordered these because my usual ones come from the USA and I can honestly say I’m glad I did because they are very good. My teeth are very sensitive and these were perfect, no after pain drinking hot or cold drinks and whitened almost immediately.

"The only downside for me was the mouth guard I couldn’t use because it was enormous and very hard but it really is not needed. I will definitely be ordering some more."

There are other popular teeth whitening products on the market, and different formats too. One of the most popular options is MySweetSmile's Dentist-Approved Teeth Whitening Powder, although it doesn't have as many reviews as Dr Dent's strips.
