Is a cleaning every six months really necessary? Learn how often you should get a dental cleaning, who needs them more often, and what to do if it’s been years.
The honest answer is that six months is a useful starting point. Some people do well with less frequent visits, and many people need cleanings more often than they realize. Here is how to think about the right schedule for you, and what to do if it has been a long time since your last visit.
Individualized care, expertise in general anesthesia, and attention to detail are why we keep returning for our son.

The dental anesthesia center is hands down the best dental office I have ever been to. I neglected my teeth for years due to severe dental anxiety. I had work done under anesthesia with doctor hoffman who did an amazing job. Doctor Behl is not only a fantastic dentist but one of the nicest people I have ever met. The dental hygienists are both thorough and gentle. Stop your search and just go here
Response from the owner:Thank you for your incredibly kind words! We’re so glad our team could help make your experience comfortable and positive. We truly appreciate your trust and recommendation!
I had a great experience at the Dental Anesthesia Center. The reception area Personnel the Doctor-Dentist and one of his assistants all helped to make sure I was comfortable, informed and ready to get it done! Thank you Dental Anesthesia Center team!! CB
Response from the owner:Thank you for your kind words! We’re so glad our team could help make your experience comfortable and reassuring. We truly appreciate your 5-star review!
Their staff was truly caring and respectful in everything they did. The dentist explained what they found in the initial tests, asked us questions about our 82 year old sister, then explained the options that would give the best results.
Response from the owner:Thank you for your thoughtful feedback. We’re grateful for the opportunity to provide compassionate care and appreciate you taking the time to share your experience.
My hygienist, DeLaina Joost, takes excellent care of my teeth with her advanced skills, gentle touch and great “chair side” manner. She is a consummate professional, and such a compassionate person. I look forward to my visits at DAC!
Response from the owner:Thank you for your kind words! We’re so glad to hear you had a positive experience with our team and appreciate you taking the time to share your feedback.
Devon’s has received his dental services here for several years. The staff are always pleasant. Dr. Hoffman unmatched. His bedside manner is always welcoming. Devon receives amazing care and support based on his assessed needs. Feedback and instruction is clear and detailed. Follow-up is greatly appreciated. I appreciate their acceptance of differences and assurance that Devon will be taken care of.
Response from the owner:Thank you for your kind words and continued trust in our team! We’re grateful to be part of Devon’s care and truly appreciate your thoughtful feedback.
Best Dentists in St. Louis. Really a great dental experience. I have used this office for regular dental care, cavities, crowns, and cosmetic dentistry. Teeth look great.
Response from the owner:Christopher we apologize for the belated response. We are very pleased to hear you have a great dental experience with our office! Thank you for your kind words. We look forward to seeing you at your next dental appointment!
Dr. Behl!
I cannot recommend Dr. Maris Behl enough. If you have dental anxiety, she is truly the kind of dentist you hope to find. If teeth could be wrapped in pillows and protected by flying unicorns, Dr. Behl would somehow make it happen.
I have significant anxiety around dental procedures and have needed deeper sedation for dental work in the past. From the beginning, Dr. Behl took the time to listen to my concerns and made me feel genuinely heard rather than dismissed or rushed. She created such a sense of trust and safety that I was eventually able to have my dental work done with only nitrous instead of full sedation, which is something I honestly didn’t think I would be comfortable doing.
During my crown placement, she explained what she was doing throughout the procedure, which made an enormous difference in keeping me calm. She also took the time to address a filling that had been bothering me for what felt like forever — and she actually fixed the problem.
What stands out most about Dr. Behl is how safe I feel in her care. She is compassionate, patient, communicative, and incredibly attentive to how her patients are feeling. For someone with dental anxiety, that combination is invaluable.
Finding a dentist I trust this much has completely changed my experience with dental care. I am incredibly grateful to Dr. Behl and would recommend her without hesitation, especially to anyone who has dental anxiety or has struggled to feel comfortable receiving dental treatment.
Response from the owner:Thank you for such incredibly kind words! We’ll be sure to pass this along to Dr. Behl. We’re pretty sure the flying unicorns are going to be the part she remembers most! 🦄💙 We’re so glad our team could help make your experience a more comfortable one.
Dr Thoms and his team are phenomenal. No question, the absolute best possible option for my child when he needed work done while sleeping (age based). While this option is not inexpensive, this set up of have anesthesiology in-house allowed us to get his mouth healthy when a traditional pediatric dentist could/would not. I am a parent that asks a lot of questions on behalf of my toddler’s care and at no point did I feel judged for this, nor was I rushed during my evaluation process during the consultation. Although the procedure is not one I would like to repeat for my child, my husband and I were both so pleased with how well Dr. Thoms communicated and how he clearly cared for our son’s wellbeing (both physical and emotional during a less than comfortable visit). Cannot recommend the back of house team more highly.
My one detraction is the FOH staff (not everyone) were not nearly as pleasant. I would like to communicate that while their day-to-day is very routine for them, being in that office as a parent is very scary for some people in their office and a little bit of kindness goes along way. I do recall, having a very pleasant conversation with Rebecca, but otherwise everyone else was on the apathetic side, in my personal opinion. That said you’ll notice that I still am leaving a five star review because the dental staff really just knocked out of the park, but as a parent I want to encourage you to look past any rudeness you may experience over email or on the phone because Dr. Thom’s is really that excellent.
Response from the owner:Thank you for taking the time to share such thoughtful feedback. We’re grateful to hear that our team provided compassionate, attentive care and took the time to answer your questions throughout the process. We also appreciate your comments regarding your experience with our front office team and will certainly share your feedback. Your kind words mean so much to us!
I have Autism. I had my caregiver call ahead to give them a heads up. It was ignored. The building sits on the highway with major traffic next to building. The building is under construction and the inside of building was a mess with workers, trash and construction equipment everywhere. I tried to use restroom but it was filled with loud workers from building hanging out. I sat in waiting room for 45 minutes while another mentally challenged individual was very loud next to me the entire time I waited. The waiting room had debris all over the floor as if somebody spent hours moving ceiling tiles. When I was finally taken back it was by a person in training. They led me to a back area of office and asked me to sit in a seat. The building is completely open. They have nothing deviding you from seeing, hearing and being in the way of other patients. Just walking through the office I almost bumped into patients having work done. They have absolutely no privacy in this building. The floor of this dental practice was littered with trash. I took photos.Clients be warned! This is not set up for patients with anxiety. This is not set up for people with autism . This dentist is not set up for any sort of privacy at all. This is not a dentist for you if you like things clean. When I explained to staff I needed to leave, I explained to them why. Yet, they made me sit and wait for an office manager. After waiting 30 minutes I got up and left on my own. On my way out I could not find the exit. I walked around office while patients were getting work done. I almost bumped into numerous objects, dentist helpers and patients. This place is UNSAFE! Never have I seen somewhere that advertises for autistic patients and they have the office SET UP Like this. BEWARE! STAY AWAY IF YOU WANT PRIVACY! STAY AWAY IF YOU HAVE ANXIETY! STAY AWAY IF YOU ATE AUTISTIC! YOU HAVE BEEN WARNED!!!
Response from the owner:Thank you for taking the time to share this feedback. Privacy laws prevent us from discussing any individual's experience, but we want to speak to the concerns raised. Our office is set up as a surgery center, and our open layout is intentional. It allows our clinical team to maintain clear visibility and respond quickly, which is essential for patient safety. Our building is currently undergoing renovation, and we know the construction has created noise and conditions that do not reflect the environment we work hard to provide. That work is expected to be complete by the end of the year. We proudly care for patients with special healthcare needs and high anxiety, and every patient is welcome in our office. Anyone with concerns is welcome to contact our office manager, Marie, at 314-862-7844.

Response from the owner:Thank you for your kind words and recommendation! We’re so glad our team could help make your experience feel comfortable and supportive. We truly appreciate your 5-star review!
Searching for a new dental clinic is challenging for someone who has
dental anxiety, fear, and traumatic experiences in a dental chair. The staff and doctors at the Dental Anesthesia Center were immediately very welcoming. Dr. Thoms put together a very detailed plan to repair and replace the previous work that I had in the past that was now causing problems. Putting my faith in him was the best thing that I could have done for my situation. I am more than completely satisfied with all of the extensive dental work that I’ve had with Dr.Thoms. I had my fourth sleep dentistry experience yesterday and I’m very happy with my results. I highly recommend this practice and truly want to give them more than five stars! Thank you for giving me back my health and confidence.
I adding to this post because of my visit today with the best dental hygienist Delaina and my exam with Dr. Biehl. I have truly never been to such a caring and supportive dental group. Everyone is always conscientious of my needs and knows that I have issues with anxiety. I am always calm when I am sitting in the chair because of their kindness. I am so pleased with the Dental anesthesia center. There needs to be more than five stars. Thank you, everyone.
Response from the owner:We know it isn’t always easy to find a dental office where you feel at ease, so your words mean the world to us. We’re so glad you feel comfortable with our team and truly appreciate your trust and recommendation!
I am unusually tense about my appointments. However, from the moment I checked in I relaxed. The staff was welcoming and assuring, and helped me to relax completely. Dr. Hofmann is superb. He is by far the best dentist and dental surgeon I have ever ever experienced.
Response from the owner:Thank you for your kind words! We’re so glad our team helped create a welcoming and comforting experience. We appreciate you sharing your feedback!
I cannot thank this clinic enough for their amazing care. They completely accommodated my individual needs by letting him wait in the hallway where he had more room for his feet and space to pace. Instead of forcing him into a tiny exam room, the dentist came out to the hallway to check his mouth. It made the entire visit so much easier for him. Fantastic service!
Response from the owner:Thanks so much for your kind words! We're grateful for the opportunity to provide compassionate, individualized care and appreciate you taking the time to share your experience. Wishing you all the best!
Great experience! The staff went above and beyond to make my individual comfortable. They let him wait in the hallway so he could pace instead of staying in the crowded waiting room. The dentist even examined him right there. Highly recommend this accommodating team! Fantastic service!
Response from the owner:Thank you for your thoughtful review! We're honored by your recommendation and are committed to providing compassionate, individualized care for every person we serve. We truly appreciate your kind words!
Why Cleanings Matter in the First Place
Even with excellent brushing and flossing, a sticky film of bacteria called plaque constantly forms on your teeth. Any plaque you miss hardens into tartar (also called calculus) within days, and once it hardens, no toothbrush can remove it. Only professional instruments can.
Tartar buildup along and below the gumline irritates the gums, and that irritation is the beginning of gum disease. Early gum disease, called gingivitis, is usually reversible with professional cleaning and good home care. Left alone, it can progress to periodontitis, where the infection damages the bone supporting your teeth. That damage is not reversible, and it is one of the leading causes of tooth loss in adults.
A cleaning visit is also an exam visit. Your dentist checks for cavities, cracked teeth, signs of infection, oral cancer, and problems you cannot feel yet. Most dental problems are far easier to treat when they are found early, before they hurt.
Who May Need Cleanings More Often
Your dentist may recommend visits every three to four months if you have:
Gum disease, now or in the past. Once periodontitis has developed, more frequent maintenance cleanings help keep it from progressing.
Diabetes. Gum disease and blood sugar control affect each other in both directions, so gum health matters even more.
Dry mouth, whether from medications, medical conditions, or age. Saliva is your mouth’s natural defense, and less of it means faster decay.
Braces, extensive dental work, or physical difficulty brushing, including patients whose disabilities make home care challenging.
Some patients with excellent gum health, low decay risk, and consistent home care may be fine at a comfortable six-month rhythm, and occasionally a dentist may suggest a longer interval. The point is that the schedule should come from your exam, not from a calendar rule.
What If It Has Been Years?
Here is the part that matters most to many of the patients who find their way to our office: what happens if it has been three, five, or fifteen years since your last cleaning?
First, you will get no lecture from us. People stay away from the dentist for real reasons, including fear, past trauma, embarrassment, severe gag reflexes, disabilities that make visits difficult, and busy, complicated lives. Whatever the reason, the answer is the same: the best time to come back is now, and it is nearly always less bad than you fear.
After a long gap, you may need what is called a deep cleaning (scaling and root planing), which removes hardened buildup from below the gumline. For patients with significant anxiety, sensitive teeth, strong gag reflexes, or extensive buildup, this can feel like a lot to face while wide awake. That is exactly why our practice exists. At The Dental Anesthesia Center, cleanings, deep cleanings, and any needed treatment can be completed under sedation or general anesthesia, often in a single visit. Years of postponed care do not have to mean years of appointments to catch up.
The Real Rule of Thumb
See your dentist regularly, at whatever interval your dentist recommends based on your gums, your health history, and your risk factors. For many people, that is every six months. For some it is more often. And if it has been years, the schedule that matters is simple: one appointment, booked.
