Dental fillings (also known as restorations) are a way to restore teeth damaged by decay back to their normal function and shape. It helps prevent further decay by closing off any cracks or spaces where bacteria can enter. There are a variety of filling materials available including gold, silver, plastic and porcelain.
Highly effective in preventing decay on the biting surfaces of your chewing teeth, dental sealants involve a simple procedure in which a tooth-colored acrylic "coating" is painted onto the surface of the tooth. This effectively seals the deep grooves, acting as a barrier and protecting enamel from plaque and acids.

They strictly enforce mask policy here. My wife had to sit in the car while our three children were seen. When they were finished, they sent the two older children out by themselves and the youngest (4 yo) was brought out by a hygienist. The dentist never bothered to come out or send anyone out to inform my wife of the older children's results. Very unprofessional.

The staff greeted me with my name right when I walked in the door. The Hygienist was friendly, gentle while cleaning my teeth and did a great job! Dentist was also pleasant and asked if I had any questions or concerns. I like the tv being on for distraction. Highly recommend!

Super impressed with the care I received from Mike H yesterday during my root canal. Even after a couple hours of the procedure the lidocaine wore off and I could already tell it was more comfortable than it had been the last 8 months. Thank you so much! You guys are great.

I had a major dental emergency this past Friday afternoon. Oshkosh Smiles provided immediate and quality care and attention even though they were CLOSED Friday afternoon. Also a quick check up appt Monday morning to insure all is really ok. I couldn't have asked for more. Note I am a relatively new patient to the practice and was treated so efficiently and well. To say the least, I presented as a very distraught patient. Oshkosh Smiles gets 5 BIG STARS for quality care and high service level.

My whole family (and now our significant others and children) have gone to this dentist office for as long as we can remember. They are very friendly and know all of our names. They make going to the dentist a great experience - it's not scary at all! My 4 year old son even looks forward to going to the dentist. I recommend this place to everyone I know looking for a dentist.

When my now former dentist wouldn't even answer their phone (leave a message only) Oshkosh Smiles fit me in the next day and everyone was very friendly, professional and took care of my needs in a timely manner.above and beyond. I am very thankful and grateful for them! Would highly recommend.

Mike and staff are a good group. They work well as a team and I trust their expertise. Most of my appointments over the years with them have been regular checkups with nothing unusual, but they've put a couple crowns on my teeth and they've fixed some fillings. They've always done good work and are pleasant/personable.
