    Patient Reviews

    I went in to have my veneers replaced- after 12 years they weren’t looking so great.

    From the online consultation, to the same-day procedure (totally painless and stress-free), Aviva were fantastic.

    I had 100% confidence in Dr Caplan at all times, and my teeth have never looked better or more natural- there’s no way you could tell they’re veneers at this point which is exactly what I wanted. I’m a very happy customer indeed.

    Absolutely first class!

    Dr Caplan put me at complete ease, and discussed my options without being pushy.

    I am over the moon with the results! Would highly recommend.

    I would recommend this practice as it’s welcoming, it’s modern and the technology Julian uses is the best in the country!

    The digital scanner that was used in my mouth to take the impressions of my teeth was painless and quick. It also meant that the imagery went straight to Invisalign and the whole experience was seamless and very fast.

    Everything was done in one day which I think is just amazing! Dr Caplan uses this latest technology, which I think is probably what enables it to be done in one day, painlessly and without discomfort at all.

    I came along at about 8 / 8.30 one morning and the whole job was finished by about 4.30/5 o’clock.

    I would certainly recommend this practice and I have recommended it to many friends and family because I believe it’s probably the best place to come if you want to improve everything about your teeth from a smile perspective and probably from a medical perspective.

    “I found it uncomfortable to eat because of two fractured teeth, so I had implants to replace them.

    After having the implants I was able to eat again and had no discomfort!

    Since then everything has been well, and I have the knowledge that they’ll last for many years.”

    Brilliant! My disgusting white and metal crown has been removed with no pain, no hassle and replaced with a beautiful looking Cerec crown.

    Nervous patient, no reason to be. Proactively going to crown another tooth as the experience was so good.
