Jackie Stokes, from Burton-upon-Trent, said she spent Â£9,500 on implants in Hungary but an investigation found her treatment plan caused "irreversible damage to otherwise healthy teeth".
Dentist Dr Zsolt Csillag was given a one-year supervision order by the General Dental Council.
He did not respond to attempts to contact him.
The Forest and Ray Medical Care Group said he had left the company due to "personal reasons".
The clinic said it "always puts patients first" and treated Mrs Stokes with extra care, above and beyond its normal routine.
Mrs Stokes said: "It has left me feeling like I have been assaulted, butchered and robbed of my life savings.
"I was advised by an NHS dentist to go down the implant road... because it wasn't on the NHS I would go seek help elsewhere.
"A friend of mine had been over to Hungary so we decided to go down that line," the 65-year-old added.
Mrs Stokes had implants in her upper jaw and crowns on eight teeth in her lower jaw, over two trips to Budapest.
On her second visit in June 2013, she said she was left with a "bulldog bite" - a gap between her gums and upper teeth through which food would seep.
The implants failed and were later removed. She now has to wear dentures.
In total, Mrs Stokes said she had 27 visits to the dental group over four years.
The General Dental Council found Dr Csillag should not have put crowns on her eight lower teeth because they were healthy.
In relation to Mrs Stokes and another patient, his treatment plan for them included "irreversible damage to otherwise healthy teeth", the investigation found.
The restrictions placed on Dr Csillag can only be imposed when he is working in the United Kingdom.

Steve Wilson: "With Craig Shakespeare bidding to become the first British manager to win his first four Premier League games, Leicester suddenly look to be only a couple of victories away from safety.
"How they would love to have those points chalked up before tackling Atletico Madrid in the Champions League.
"Stoke are having another very creditable season; ninth place again at the moment - the position in which they have finished each of the last three seasons.
"Mark Hughes would have particularly enjoyed their point at Manchester City in their last away game, but would probably concede that they have, at times, been too accommodating on their travels - registering wins at only Hull, Watford and Sunderland."

Leicester manager Craig Shakespeare: "With all the records, I'm very conscious you have to keep a bit of humility about it.
"We know that it wasn't so long ago that our form was being questioned.
"We know that at the moment we are playing with a lot of confidence, but that word 'humility' has to be important from my point of view towards the players to keep them level-headed. We also (like) to make sure there is no complacency."
Stoke manager Mark Hughes: "It's difficult to win away games in the Premier League. The most we've achieved in a season is six.
"More often then not we take games to the opposition and look to win. We'll see where that takes us over the remainder of the season.
"Leicester are playing well at the moment. They are a fully committed side. We need to ensure their key players don't have an impact."
I fancy the Foxes to win this. Stoke have had some mixed results of late, and although they won't roll over I don't see them stopping Leicester's momentum.
