Kristen Tavares, 23, is still on a breathing machine and in a coma at the Maui Medical Center. 
 
 "We did find out they did do a CT scan. The brain right now is a little swollen," said Joe Tavares, Kristen's father. 
 
 The mother of two young children went in to have her wisdom teeth removed on Monday and didn't wake up. Her dad happened to be on Oahu today for his own medical appointment. 
 
 "It's a lot of stress on everybody right now," said Joe Tavares. 
 
 Dr. John Stover does a lot of procedures, everything from cosmetic to plastic surgery in addition to the oral surgery. His medical and dental licenses are in good standing. 
 
 However we discovered Dr. Stover has had four previous complaints with the state since 2010. Two complaints for "failure to comply with laws governing professional conduct" were resolved without enough evidence. Two other complaints from 2012 and 2013 are still ongoing. 
 
 He has also been sued for medical malpractice, however that case was dismissed. 
 
 Sources say Dr. Stover requested the use of full anesthesia for his dental practice in 2005, however that was denied. In 2007 he was granted the permit to use "intravenous-conscious or moderate-conscious sedation." 
 
 On his medical license he is allowed to use full anesthesia. Since oral surgery, including wisdom teeth extraction, is considered a medical procedure he would be allowed to use full anesthesia if necessary. 
 
 The section regarding anesthesia on his website says it is in development. 
 
 Today we spoke with the 17 year old girl who had her wisdom teeth removed by Dr. Stover right before Kristen Tavares. 
 
 "I just saw them stick something in my arm and I don't remember what happened after that," said the patient who requested we not use her name. "It's a scary thought because, to know that I went through the same procedure as she did, that it could have been me that couldn't have woken up, it's just really freaky." 
 
 Tavares was alone in the dentist's office and Dr. Stover hasn't returned our calls so it's unclear what exactly happened. 
 
 Experts say problems often start when breathing stops. 
 
 "Statistically it's usually an airway issue," said Daniel L. Orr II, DDS, Professor and Director, Oral and Maxillofacial Surgery and Anesthesiology at UNLV. "Perhaps a foreign body drops into the airway like a tooth, or a piece of gauze or perhaps the patient might vomit and get fluid up their airway and then down into their lungs. That's why we have them don't eat or drink before a general anesthetic or any anesthetic." 
 
 Today the Tavares family is focused on recovery rather than blame. 
 
 "Right now all we are doing is praying and hoping for the best," said Joe Tavares. 
 
 Tavares' family says they weren't given a timeline. Right now it's a waiting game on her recovery.

 A 23-year-old mother of two small children from the Big Island went into a coma and then on life support at Maui Memorial Medical Center following a visit to a Hilo dentist’s office on Monday. 
 
 Kristen Tavares reportedly went into cardiac arrest while undergoing a procedure to remove four wisdom teeth at the office of John Stover, a self-described cosmetic surgeon who state records show is licensed in Hawaii as both a medical doctor and a dentist. 
 
 State records available online show that Stover has been the target of three medical complaints with the Department of Commerce and Consumer Affairs, two of which are pending. The other one, from 2012, alleges that Stover failed to comply with both licensing rules and laws governing professional conduct; the department’s Regulated Industries Complaints Office, however, didn’t find sufficient evidence and no action was taken, according to state records.
– A Hawaii woman went in for routine dental work on Monday but ... didn't wake up. Kristen Tavares, 23, was to have four wisdom teeth removed; during the procedure "she went into cardiac arrest and they had to use a defibrillator and shocked her, stunned her heart," her boyfriend tells Hawaii News Now. The mother of a three-month-old baby and a son, 4, is now in a coma, and a CT scan shows some swelling in the brain, a separate Hawaii News Now story notes. What went wrong still remains a mystery. "Statistically it's usually an airway issue," a doctor not related to Tavares' care explains. "Perhaps a foreign body drops into the airway like a tooth, or a piece of gauze or perhaps the patient might vomit and get fluid up their airway and then down into their lungs. That's why we have them don't eat or drink before a general anesthetic or any anesthetic." Cosmetic surgeon John Stover treated Tavares; he has both medical and dental licenses. While he's in currently good standing, Civil Beat dug up state records that show Stover has had three medical complaints against him; two are pending, one from 2012 related to professional conduct was dropped due to lack of sufficient evidence. (Last month, a Maine teen mysteriously died three days after having his wisdom teeth removed; a month prior to that, a 3-year-old died after a dental procedure in Hawaii.)
