Metal Free Dentistry
Metal-free restorations are crowns, bridges, and fillings that do not contain any metal. Metal-free crowns and bridges are usually made out of dental porcelain (which is otherwise known as dental ceramic). Metal-free fillings are made out of a flexible resin that contains tiny particles of glass and plastic.
Metal-free restorations can be used for all of the same purposes as their traditional metal counterparts. For example, they are excellent for stopping dental decay, protecting damaged or weak teeth, and replacing lost teeth. In some cases, metal-free restorations are used solely to improve the appearance of a patient’s smile.
How Do Metal-Free Restorations Work?
To place a metal-free restoration, a dentist must select the best color for the restoration and then prepare the tooth that will receive it. This preparation often involves removing areas of decay and/or shaping a tooth so that the restoration will not look bulky or unnatural. If you are going to receive a crown or bridge, our team will need to take some impressions of your teeth. Your dentist will send those impressions, along with detailed design notes, to the laboratory that will create your restoration. Once your restoration is ready, your dentist will verify that its color, shape, and size are perfect before they permanently place it in our mouth.

Cost of Metal-Free Restorations
The cost of metal-free restorations is in the same ballpark as the cost of metal restorations. Our team will be happy to give you an estimate for the cost of your procedure when you visit us for a consultation. The price of your restoration will depend on the material used to make it and the extent of the necessary treatment. In most cases, dental insurance is willing to cover a significant portion of the cost of metal-free restorations.
Frequently Asked Questions
Metal-free dentistry uses tooth-colored materials - ceramic, zirconia, composite resin - instead of silver amalgam or metal alloys for fillings, crowns, bridges, and implant components. It eliminates concerns about mercury exposure, dark metallic appearance, and galvanic sensitivity some patients experience with metal restorations.
Yes. Modern zirconia (zirconium oxide) is one of the strongest dental ceramics available - strong enough for back molar crowns that endure heavy bite forces. High-translucency zirconia also offers excellent aesthetics for front teeth, making it suitable for virtually any crown location.
When done following SMART (Safe Mercury Amalgam Removal Technique) protocols - including isolation, sectioning, and suction - amalgam removal is considered safe. Oxford Smiles uses protective measures during amalgam removal. Elective removal should be discussed with Dr. Mehta on a case-by-case basis.
Zirconia (ceramic) implants are a metal-free alternative to titanium implants, preferred by patients with metal sensitivities or those seeking a biocompatible, tooth-colored implant body that will not show through thin gum tissue. Ask Dr. Mehta if zirconia implants are appropriate for your case.
Ceramic and zirconia materials typically cost more than amalgam or metal-based alternatives. However, costs have decreased significantly as the technology has matured. Oxford Smiles will provide a clear cost comparison so you can make an informed choice aligned with your priorities and budget.

Posted on SlampaProductionsTrustindex verifies that the original source of the review is Google. It’s been about 6 years since I’ve been to the Dentist due to some poor experiences in the past, and I am happy to say that my dental fears have been resolved. They were so welcoming from the second I walked in the door, through the x-rays, and cleaning. Highly recommend them to anyone looking for a new dentist!Posted on Stephanie BachnerTrustindex verifies that the original source of the review is Google. UPDATE!! I will be returning and continuing services with this practice. The doctor and her assistant today gave me a warm welcome, showed confidence in what they were doing, DID NOT RUSH, were personable , and an absolute delight. My teeth feel very good. they assured me that sometimes cleanings are fast due to proper personal care/hygiene. And that my teeth are in good shape. I’m very grateful. I will happily update this rating from 3 to five stars ⭐️⭐️⭐️⭐️⭐️. Thank you again Following up after my first visit/cleaning. Upon walking in, The receptionist was wonderful welcoming and very sweet. She has a pleasant tone , actually smiled and greeted me with inviting eye contact even tho she was on the phone at first. She quickly signed me in and told me take a seat anywhere. I love the pothos leaves and lobby. Second person of contact: The assistant, seemed nervous; and was asking me questions but not letting me finish responding before asking the next question. Maybe she thought I was younger or have never been to the dentist in my life. The questions felt rehearsed and not genuine, like they were being recited. I will say, After the X-rays everything became more comfortable. We all laughed at one point and the service went on. The Dr. was nice but I know I’ve had better cleanings. I actually commented on how fast it was? It was too fast. I was expecting to be worked on (the actual cleaning alone) for 20 min or more , not including flossing and polishing. The manual scaling was too quick and extremely light in pressure. The crevices of my biting areas were also skipped? I know my teeth are healthy. But 10000% could be healthier and is why I scheduled. I haven’t had a cleaning for two years so I know from the coffee and non tobacco related recreations I indulge, my teeth are not** brighter than pre cleaning and look the same. My previous dentist is out of regular travel now but she was exceptional took her time and gave me a thorough cleaning , I’ve been smoking and drinking coffee for 15 years and that has never compromised my finish. I don’t want to experience pain or a dentist scraping my teeth with unnecessary force for satisfaction. I’ve just simply had better cleanings. This office is very close to my residence and it’s ideal. Also it’s a nice building, clean, aesthetic is pretty. I gave Oxford Smiles a go because of convenient location and was hoping to add a more positive review. My expectations were higher as I try to lead with positivity but, besides my expectations; you all have field related experience certifications and or degrees and should be going out of the way for patients instead of only, “going through the motions.” Dental health is no joke. Thank you so much for seeing me. I’m not over the moon, yes dissatisfied, and deserve confident hygienist who enjoys each individual experience per client.Posted on Dean SimpsonTrustindex verifies that the original source of the review is Google.

Awesome treatmentPosted on Breanna BenoitTrustindex verifies that the original source of the review is Google. Amazing staff who made me feel comfortable and truly cared for.

Jennifer and this team as a whole does a great job! I bring my son here and he loves the care that they take with him and the patience they have. Thank you for going above and beyond. *******I want to continue this review by saying that upon my son going here I have started going here for my dentistry. Dr. Parmar is one of the best dentists I have ever had, she takes so much care at every turn and really thinks things through! Many years to come I hope me and my son are able to visit this dentist. Highly recommend the hole teamPosted on I RCTrustindex verifies that the original source of the review is Google. Very quick and kind staff/doctor!
