Dental365 – Port Jefferson (Formerly Gentle Dental - Port Jefferson)

Dr. Kleinman is caring and thorough and Ginny Hansen has to be the best hygienist On Long Island there’s no way that anyone can tell me that there’s anyone better than her because she has been amazing with me and with my husband she is so kind so intelligent so thorough. I love this office. I can’t say enough good things.

My fear of dental cleaning is over. Jess is fabulous and Dr Kleinman is amazing. I’ve been coming here for years and never had a problem from seeing a dentist to handling the billing. Everyone is professional & friendly. If you fear going to the dentist, see these people and you will be just fine.

Great practice! Professional and very helpful staff. Patient care is excellent and your wellbeing is the priority. Dr. Kleinman is personable and explains everything he's doing and why. I recommend unconditionally!!

5 Stars for Dr. Kleinman and his team. Been seeing him since I was a kid and despite a few emergencies, his team has been able to accommodate me. Direct, straightforward and very polite!

My experience with Dr. Kleinman today was the worst I ever had. He refused to treat me anymore after my visit today and wasn't nice about it at all. While he claimed he didn't want to upset it sure didn't seem that way. He has been treating me for several years repairing a bridge I had done elsewhere. I am a paying customer; the repairs would last sometimes up to two years. Whenever I needed a repair, I would get lectures about repairing the bridge and how he doesn't know how long the repair will last. I told him I don't care how long it lasts, please just fix it and I have no problem paying I have insurance. It's like he wants me to feel guilty he is repairing it again. I am 79 years old. I cannot afford implants, way too expensive, I do not want all my teeth pulled and have dentures.
