Often heavy metals can be contained in the dental care we receive. There is plenty of research highlighting nickel allergies from braces, wires and other orthodontic devices. Some metal dentistry devices or implants can contribute to an individual’s systemic nickel allergy. The amount of nickel from dental devices tends to be significantly less than that ingesting foods higher in nickel.

If you know you’re already hypersensitive to nickel, it might be wise to discuss potential options with your dentist and doctor. Some of the research recommends metal allergy patch testing prior to surgery, so whatever is impacted into the body doesn’t cause an adverse reaction. In September 2019, the FDA’s Center for Devices and Radiological Health published an extensive article noting the Biological Responses to Metal Implants. The brief includes information about how the the immune system responds to metal implants and the specifics of dental implants, orthopedic, neurologic, cardiovascular, and urogenital devices and the local tissue and organ inflammatory responses to metal implants.

Many of us may have had braces or received other dental care that could be contributing to our systemic nickel allergy and we may not realize this fact. Focused on what I eat and the cookware used to make it, I neglected to consider how my stainless steel retainer, cemented on my front teeth for nearly 20 years, could be impacting my nickel allergy. 

At 13 I had very crooked teeth and a massive overbite. Grateful my parents invested in me and my smile, I had braces installed when I was 13 for nearly 2 years. Little did I know that by the age of 24, I’d be diagnosed with a systemic nickel allergy. Fast forward another 10 years I’ve been working towards living low nickel. However it wasn’t until last summer when I had my first root canal that I replaced my stainless steel permanent retainer with a removable nickel free plastic retainer. In hindsight, I probably should have tried using the invisalign to correct my teeth rather than stainless steel braces. However, neither my parents nor I knew back then that I would develop such a severe nickel allergy as an adult. 

To avoid serious dental issues, I love visiting the dentist for preventative dental care. Until recently, I never used to ask my dentist to thoroughly discuss what he planned to use in my mouth and whether or not the product may contain nickel. Personally I am less worried about their tools containing nickel from stainless steel, as I only visit the dentist for 30-45 minutes twice a year. My main interest is avoiding anything being permanently add to my mouth that may contain nickel and how over time it could impact systemic nickel allergy. Luckily I only have a few fillings and I feel fortunate that a plastic resin was used. Amalgam fillings can include some heavy metals, however I cannot speak to whether nickel or stainless steel is a common ingredient that may used in amalgam fillings. 

This past summer, I chose to delay my standard 6 month dental cleaning and extra couple of months because the COVID-19 case count was at an all time high. Before my visit, I had an extensive conversation about what practices and safety protocols my dentist office is taking to prevent exposure for both their patients and staff. Their protocols put me at ease and I finally got my teeth cleaned, last month, where the oral hygienist ravaged my gums for nearly an hour.

Besides seeking preventative dental care, what else should you consider when caring for your overall oral health when living with a nickel allergy?

Unfortunately many toothpaste products contain additives, sugars, and sodium lauryl sulfate (SLS), a cheap bubbling agent added to many cosmetic products. Using products that contained SLS sensitized and irritated my scalp and gums. I also try my best to avoid unnecessary additives or ingredients high in nickel like soy, oats, nuts or seeds. I can’t eat coconut, but I haven’t had any issues using either toothpaste or shampoos that contain coconut derived ingredients.

I use this Burt’s Bees Extra White with Fluoride Zen Peppermint (affiliate link). Burt’s Bees does offer a similar toothpaste without Fluoride. Both include coconut ingredients, but their toothpaste does not include many of the other terrible fillers found in other toothpastes. 

Consistent when seeking any health care, you have to be your own advocate and inform your providers of your severe nickel allergy. This may involve preparing before your visit to identify a list of questions you want answered. These questions may need to include what companies or manufacturers your dentist partners with to verify whether or not ortho-device or product is nickel free. 

If you’re concerned about what’s in your mouth, it’s best to consult a dental health professional, including a dentist, endodontist or orthodontist.

  1. Hi Christy, I just found out today through patch testing that I am very allergic to nickel. I requested the test because I developed severe dyshidrosis (eczema on my hands and other body parts) 4 months ago and I eventually connected the dots, realizing that it might have been caused by the nickel orthodontic brackets that got put in my mouth just before my skin flared up. Three different doctors told me that it was extremely rare and was not the cause of my skin issues….. until I got the results back today proving my theory. I am not sure yet if I am allergic to foods high in nickel (I want to look more into that), but my question is how do you tell if nickel is in certain products? I get really terrible rashes from most deodorants (which makes sense now as I assume they have nickel) so I was just in the store trying to find a brand that had no nickel but I could not find any indication on the label or by googling it. How do you go about making sure you avoid high nickel products/items/cosmetics? Thank you

    1. Hi Sabrina,
      Thanks for your comment. Unfortunately labels on cosmetic items or food items don’t tend to mention whether or not the product contains nickel. There are general guidelines for cosmetic for people with eczema including avoiding fragrances and preservatives. Then I also avoid cosmetics that contain ingredients known to be high in nickel such as oats and nuts like shea butter. I write a little more about this
      Warm regards,

  2. Thank you for your research. I recently had my fillings removed as I realized that the growing, painfully itchy rashes I’ve developed all over my body over the past decade were a result of my nickel allergy, and my fillings were to blame. Since having them removed my rashes have been clearing, but I noticed they were being triggered by certain foods. That’s when I discovered systemic nickel allergies. Adhering to a low nickel diet has helped tremendously with the itchiness and inflammation I’ve been dealing with but there are days that I just don’t know what to eat. I’m lactose intolerant as well, so having to stay away from the nut and soy based dairy-free products I’ve been accustomed to feels discouragingly limiting at times. Still trying to sort this all out., but your blog is very helpful.

    1. Hi Erika,
      Thanks for your comment and appreciation for my website. It’s wonderful you learned that your metal filings most likely were a primary contributor to your systemic nickel allergy and were able to get them removed. Continuously eating a low nickel diet definitely can be work, I have felt it gets a little easier the longer you eat it and start to adapt recipes to be low nickel. It would be much harder to also have to avoid dairy. Have you tried Rice Dream Rice milk? I like it as an alternative to cow milk and even though it contains whole grain rice it doesn’t cause my nickel allergy to react.
      Warm regards,

  3. Hello! I also have a severe nickel allergy. I noticed your comment about SLS. I use an essential oil based, fluoride free toothpaste. When I checked the ingredients, it also has an SLS, but is listed as Sodium Lauroyl Sarcosinate (no spelling errors.). Are they the same thing?


    1. Hi Brenda,
      Thanks for your comment. I don’t know as I’m not a chemist. I researched the question online today and it appears that both Sodium Lauroyl Sarcosinate and SLS are surfactants but Sodium Lauroyl Sarcosinate is a milder surfactant so it’s less likely to cause irritation.
      Warm regards,

  4. Thank you so much for your blog. What a wonderful public service. I just became aware of my nickel allergy and am changing my diet. I am sleeping better, not itching all the time and pain free from the painful blistering. Thank you Christy. You have a new fan. Best, Eleanor

    1. Thanks Eleanor for your comment. It’s wonderful to hear my blog and how changing your diet has made such an improvement in your life.
      Warm regards,

Nickel in our Tap Water

When I was first diagnosed with my allergy, I only considered being aware of all the food I ate that could have traces of nickel. I never considered how the tap water I drink could be a “trigger,” until I read Barbara Njuguna’s personal story about how she was “nickel poisoned” after drinking tap water.
