    Best dental group ever!!!…read more When I was searching for a dentist I searched the internet pretty thoroughly. I noticed all the five star reviews for Avalon Dental! Well, Avalon lives up to their reputation. In fact they are the best dental group I ever used!!! From receptionist, to hygienist, to the dentist - they were perfect in a way that I've never encountered. I was there for teeth cleaning and I was treated as if I was a family member; and they treated my teeth like they would want their own teeth treated. They were very upbeat and transparent about pricing. I left with a great feeling and a feeling that my teeth were the cleanest they've been in a long time! I highly recommend Avalon Dental to anyone who wants the same great treatment!

    I can no longer recommend this place at all. Honestly they have just turned into scammers and…read moreliars. I had two teeth done in white gold several years ago and everything was great. I believe it was last year I did a consultation that I had to pay for. They the ghosted me and wouldn't be straight forward. The doctor reached out to me personally and apologized and told me to give them another chance. So in June of this year I went back and had to pay the consultation fee AGAIN. Its now been two months of chasing them and now they want to send me a quote for double what I was told. Thats it, im done. Do not go to these people. They are an absolute joke.

Let us suffer and wish to chew on rocks to destroy the ugly lazy work you created that doesn't even let a person smile the same anymore as I said you are selfish monsters that hide behind good manners like any other monster typically does to torture people.so thanks for your torturing I will not ever forget it also tell dusty people have lives she's not a judge or prison guard she's a damn pencil pusher and nothing else.

    I cannot recommend White Clay Dental Associates strongly enough. My daughter is a student at the…read moreUniversity of Delaware, and experienced somewhat severe dental trauma just a few weeks into her freshman year. As I drove to Delaware to be with her, my wife searched for a local dentist. Thankfully she found White Clay. The entire staff was extremely caring, understanding, and concerned. They treated my daughter as their own. Dr. Ganfield has gone above and beyond in his care for my daughter, creating prosthesis when needed, and devising ingenious methods of treatment. His gentle, reassuring manner went a long way towards keeping our family sane during this crisis. The group goes out of their way to ensure that our daughter can get timely appointments that work with her schedule, and she doesn't spend much time in the waiting room. I wish I had such a dental group located near me, because I've never encountered a finer one. If you are looking for dental care in or around the Newark area, you can do no better than White Clay.

They waited last minute to advise this so they could make money. Shady practice. When I was seen here it was great but the customer service skills SUCKS.

The front-desk and billing staff are in constant flux. At my last visit for a routine cleaning, I was assigned to a new-hire who was clumsy and ended up choking me. I stopped the appointment and came back the next week when a hygienist I'd been using for years was able to see me. She and I have always been on good terms. I expected her to apologize for the prior week's fiasco with the incompetent new-hire. But when I sat down in her chair, she started an angry tirade criticizing me for being so mean to the new hygienist! I was shocked. When I asked to speak with Dr. Young, she cold and unfriendly, more interested in protecting her young new-hire than in my needs as a patient. It was all so unprofessional and weird. I left vowing never to return. There are many excellent dentists in our area. I found one of them, in Middletown. No reason to go to this third-rate dental practice.

    It has been some time since this experience, but I told myself I would write a review after a…read morenumber of months had passed, and I cooled down a bit. Honestly, as I write this, it is not very fun to recall, but I hope the Doctor will read this, and this will help future patients. Type of Care: Adult wisdom teeth removal Care Quality: To be absolutely clear, the doctor was excellent. The work he did was done very well, and there were no complications after the procedure. He was awesome and a great personality. Office Experience: #1 - walked in for the appointment, and they said we had canceled it. We never canceled it. People don't prep and show up on time for wisdom teeth removal appointments if they've canceled them. Their office staff had, from what we could decipher, been the ones who erroneously canceled the appointment on the same date and time that they had called us weeks earlier SOLELY for the purpose of telling us how much our out-of-pocket would be. There was no discussion whatsoever during the call about whether or not we were proceeding with the appointment. We were proceeding with it. The doctor, being a professional, thankfully managed to keep the appointment as scheduled. No problems there. Thank goodness, because who wants to prep and come back again to have their wisdom teeth removed?! Again, this doctor is very good! That leads to #2 - during that call weeks earlier, again the sole purpose of said call from them to us was to relay our out-of-pocket cost, the lady said the cost to us would be $50. $50. 5-0. We made them repeat that numerous times, and the lady said, "yes, great deal isn't it? Your insurance must be good! We'll see you on your appt date...Us: yes, we'll be there." Soon after the procedure, we got a bill for well over $1,000 out of pocket! After a lot of back-and-forth with the office and our insurance company, the cost came down to $900. In the end, this was the correct cost to us based on the way the office coded the procedure (coding...very impt factor - please take note) and what our insurance policy would cover. The office staff would not concede any miscommunication or misinformation on their part. It was both shocking and disheartening to be treated the way we were. So, just beware. Most important moral of this story is make sure you, as the patient, do ALL the research on how much your procedure might cost you out of pocket, because unfortunately, the office staff failed in that regard. You can't rely on their word. They do not know. They don't have any idea how the procedure might get coded, medically, in advance of it, and maybe the doctor and the nurses can't even predict that -- and that is what the office staff should have told us, but didn't. They should have been honest about what they knew and what they didn't, but they weren't. Their actions unnecessarily led to a lot of heartache, headache, and financial surprise.

After we exchanged a few words, I simply asked for a invoice of the treatment so I could get a better understanding, when I received my letter the envelope was ripped and scotched taped together with a post it note that read "fax as*hole".

Dr. Erin is amazing, caring, professional, and always makes her patients feel comfortable. I was originally a patient of her father, so it means a lot to continue receiving such excellent care from the next generation of this practice. The entire staff is welcoming, friendly, and truly cares about their patients. They have also become the dentists for my children, and we have always had great experiences here. I have never had any issues with Dr. Erin or the office. A special shoutout to my dental hygienist, Chris, who is absolutely wonderful. She is extremely thorough, detailed, and gentle during cleanings, and she always takes the time to make sure everything is done perfectly. I highly recommend this practice to anyone looking for a trustworthy and caring dental office!

Thank heavens for Dr. Erin Cox at Main Street Dental and the friend who recommended her. She called my mom back on her cell phone on the weekend, got her in for an emergency visit the next morning at 7:30am, and gave my mom enough help that my mom could wait until she returned home for her root canal (lucky Mom!). My husband and I then went to Main Street Dental for the rest of the 3.5 years we lived in Newark. The entire staff is very friendly, and Wendy the hygenist is terrific. Unfortunately for me, I somehow always ended up with substitute hygenists, so I didn't get to have Wendy clean my teeth until my very last visit, which was too bad, because she's great, and the subs weren't all quite so gentle--plus, it's really disconcerting to always end up with a new hygenist every time you come in (at least, it was for me). Dr. Erin does a great job cleaning and will clean your teeth if you request it. She did fill a few of my teeth, which was new--I hadn't had any fillings before going to her. But I felt she did a good job.
