Retainers

Orthodontic retainers keep your teeth from shifting. Even if you had teeth straightening treatments like braces when you were younger, your teeth will naturally shift over time. Wearing a retainer at night can maintain a healthy bite and beautiful smile.

Oak Tree Dental can help you keep your smile straight and your teeth even with the use of orthodontic retainers. A retainer helps keep your teeth in place after you’ve had braces or aligners, as either a temporary or permanent answer to stop teeth from shifting back into old positions. 

Retainers are part of post-orthodontic treatment designed to maintain your new, straight bite and smile, and it’s important to use them correctly according to your orthodontist’s or dentist’s instructions. Poor or improper retainer use after braces can undo all the good work that was done and damage your final results. At Oak Tree Dental, we don’t offer traditional braces in our offices, but we are happy to help oversee your retainer care as part of your lifelong dental care.

Types of Retainers

Different types of retainers may be recommended for you depending on what your dental health professional thinks will work best in your individual case. You also may not need braces at all, but will benefit from just using a retainer to fix more minor alignment problems. 

Clear retainers are transparent tray-like retainers, similar to clear aligners like Invisalign. The difference is that they are usually prescribed after orthodontic treatment, and may be worn less frequently. They are removable and are placed over your teeth to keep them in their new places. 

A more traditional retainer is made of plastic or acrylic and wire, and fits inside your mouth, usually on the top, to put pressure on your teeth and maintain their new positions. Another option your orthodontist may use is a sublingual bonded retainer, where a wire is fixed to the inside of your bottom front teeth to maintain their shape and position. 

Good Retainer Care

Wearing your retainer as instructed is the most important concern for patients, to make sure your teeth don’t shift out of their new positions. But a close second in importance is keeping your retainer clean and healthy. Anything that is going to be in your mouth for large amounts of time should be kept clean with a regular hygiene routine. Here are a few good guidelines to ensure your continued good dental health while using a retainer:

  1. Whenever your retainer isn’t in your mouth, it should be in its case to avoid bacteria, dirt and foreign particles.
  2. Keep the case and the retainer clean with regular rinsing, brushing and disinfecting to be sure you aren’t trapping bacteria and grime in your mouth. 
  3. Use cold or room temperature water to clean your retainer, since hot water can deform softer plastics and weaken the retainer’s ability to do its job.

It’s common for patients to need to wear their retainers for up to six months daily after getting their braces off, and we may recommend that you continue wearing it at night for a longer period of time after that. Individual patients’ time frames for retainer use vary, and how long you will need to use one depends on many personal factors, including how well and quickly your teeth and gums adapt to the changes made by orthodontic treatment. 

Get in touch with Oak Tree Dental if you have questions about what we can do to help you maintain a straight, healthy smile for many years to come.

I had such a great experience with Dr. Navarette and his team! The service was amazing and the atmosphere felt really welcoming. Everyone was so friendly and made sure to answer any questions I had. They’re incredibly thorough and explain everything step by step, which helped me feel super comfortable throughout the whole visit.I also really appreciate how clearly they plan out your care. If anything extra needs to be done, they walk you through the next steps in a way that makes everything easy to understand. Their communication is excellent, and it honestly makes the whole process feel stress-free. Highly recommend!

Everyone at Oak Tree is always so nice and welcoming. Monique up front is great, very helpful and always sweet. All of the hygienists and doctors are very gentle and have helped my fear of the dentist immensely. Both Dr. Grados and Dr. Navarrete are personable, kind and light handed. Very grateful to have found a great dentist!

We’re new to the area and new to the practice. I had an onlay done and I couldn’t be more satisfied. The onlay was fitted and formed all in one session using the latest technology. Quickly and efficiently and all with the best “bedside manner”.

My best experience ever with a dentist and I've had many. Dr. Gardos and his staff were superb to work with, very professional, kind and caring, and willing to explain things fully and work out a plan that worked for me. With their very latest imaging techniques, they were able to make a crown within 40 minutes that fit perfectly! Such a relief to find such care. Highly recommend.

They’re the very best! Every time I get any kind of treatment from Oak Tree Dental, I leave feeling so well cared for and extremely grateful. I’ve seen many other dentists in my life and not one compares to the level of expertise and ease that I’ve received from this place. I can’t recommend them enough!

I suffered a TBI with neurological Lyme disease for many years. I wasn’t able to withstand getting fillings. Lyme disease is very destructive to enamel and collagen so my teeth were quite the state. My nervous system and my brain were also still healing. I saw one technically excellent dentist in Occidental, who was emotionally unable to cope with my situation. His lack of empathy and hostility and dismissiveness… I don’t think I can express the impact when you’ve already been through so much. I was shocked, horrified, and I also knew I was right next to needing a root canal and this dentist dismissed me like I was an annoyance. And thank God he did. Because he was a terrible soul. And then I met Dr. Grados at Oak Tree dental. He was so kind, he was so present and calm. He listened and watched me, where he didn’t understand, he was keen to learn and fascinated. He enjoyed his work. He was diligent and happy, even as we found a way to manage my symptomology with his goals for my healing. He is excellent in every way and you can tell from the kindness and the sweetness in the whole office that they are proud to work there, and that he has chosen each one as a reflection of what he values. If you’re out there and you’re dealing with a neurological issue, a devastating illness, or you have chronic pain no one else can see…This is the dentist to go work with. And his staff included

I have been going to the same dentist office for 56 years and he retired. I had great referrals from a friend for Dr.Grados.and his staff. So hard going to someone new but they did everything to make me comfortable. All very nice and explained everything. Also Dr. Grados took his time with me and never seemed to be in a hurry. Would recommend him and his friendly office highly. Had a lengthy procedure today and Dr. Grados did a wonderful job. He is so kind.Today I went for two crowns. Dr. Grados makes them there . No temporary’s, no coming back for permanents. Amazing and meticulous. Had my teeth cleaned by Connie. She is so lovely and kind.

I had my new patient exam with Dr. Navarrete and Andrea today, and they were a great team! Oak Tree Dental was referred to me by some friends of mine who go there. The Doctor answered all of my questions I had about my treatment; they were very clear about the timeline and what to expect, which made the whole process so much easier for me. Thank you to Dr. Navarrete and his team for being so friendly and knowledgeable. I appreciate the time they took to make my visit so comfortable. Highly recommend! :)

I'm a pretty tough mama EXCEPT when it comes to the dentist (ok and ticks too but who's not afraid of those!) I embarrassingly went wayyyyy too long without dental care out of fear. Rather getting cavities than go back.I was referred to Oaktree for that very reason and can not be more grateful. They are so, so kind. Never making me feel bad having gone so long and very attentive to my fear. Communicating everything they are doing before they do it, checking in constantly, and taking breaks for deep breaths when needed. Oaktree's helping get my dental needs back on track while making me feel comfortable and confident about going back. Big nonjudgmental, kind, nurturing sweethearts.

2021 - June I just moved here a few months before I contacted them, and was pleased that my call was returned. they told me of all the details which would be done. I also needed two crowns, etc. and the whole things was done the same day! I was surprised that they didn't send me home with two temp ones!everyone is nice and attentive.Update: I went again for cleaning and that was the best cleaning I have had for a long time.Update: 2024 This is an amazing and professional office. very caring, clean, straight, friendly, on time, and they use latest technology.

Dr. Grados and his staff are extremely competent, friendly and reassuring, the office is immaculate and appealing, the pricing is quite competitive (especially their discounted plan for people without dental insurance). Exams are thorough, in-house fabrication and fitting of dental crowns by Drs. Grados and Navarette have been impeccable.
