There are great recommendations here, but I thought I would add one more.
Before I arrived in Lima I contacted Dr. Patricio Quevedo from their website, http://www.vamosdental.com/index.htm
, because a filling I had was cracked and I was told it needed to be replaced with an Onlay soon before further damage was done. I did not want to pay the extremely high prices of my NYC dentist without insurance, so I decided to head down to South America for a visit and to get my tooth repaired here. This was such a good decision - I saved lots of money and had a great experience.
Since I began inquiring with the dental practice, Dr. Patricio has been very responsive, helpful and he speaks/writes English well, I later learned he also speaks French. He was always very honest about pricing and my options.
Once I arrived for my treatment, the service was excellent...better than any service I had received in the US. Additionally, he was able to simply replace the filling and avoid the more costly Onlay treatment. The pricing is much more affordable than treatments in the US, but the fact that he offered a less expensive, but equally effective treatment really impressed me. Additionally, he provided advice about cavities I had and if they needed to be treated now or could wait a while.
Here is his contact information:
