"I was amazed at the positive results"
Based on a study I performed at the University of Saskatchewan, I was amazed at the positive results from the use of the 1-TDC technology (unique fatty acid oils). All periodontal measurements in the test animals improved significantly. The more I use the 1-TDC technology, the more impressed.

"I recommend 1-TDC for all perio cases"
1-TDC has been a tremendous addition to our post-oral care armamentarium. Fatty acids have been documented to have anti-inflammatory properties, and I have seen clinical improvement in dogs and cats using 1-TDC (with existing periodontal issues). I prescribe 1-TDC for all periodontally-related cases, and since the palatability is so high, compliance is fantastic.

Backed by Research,
Proven by Results
Unlike supplements based on anecdotal evidence, 1-TDC is backed by 9 peer-reviewed scientific studies. We invite you to explore the research yourself.
Oral Health & Periodontal Studies
1-TDC has been evaluated in periodontal models and clinical settings for its effects on gum health.
Clinical Periodontal Study in Veterinary Patients
- A published study in cats with chronic periodontal health issues found that 1-TDC significantly reduced gum inflammation.
Although these studies were not conducted in dogs specifically, veterinarians consider the findings relevant because the underlying periodontal biology is the same across species.
Additional Published Research in Dogs (Mobility & Quality of Life)
A published field study in arthritic dogs evaluated 1-TDC chews for joint-related quality of life. After 30 days of daily use:
- 75% of owners reported improved daily quality of life
- Common observations included "happier," "more energetic," improved gait, stair climbing, and overall comfort
- The authors concluded that 1-TDC may offer an alternative to more traditional therapies for supporting joint health in canines
While this study focuses on mobility rather than oral health, it supports 1-TDC's broader role in reducing inflammation and improving quality of life — which many pet parents notice as a bonus when using it for gum support.

Your Questions, Answered
Everything you need to know about 1-TDC
Based on our customer survey, 93% of pet parents noticed improvements in oral health within 1-2 months with consistent daily use.
Most customers report seeing initial changes around the 4-6 week mark — fresher breath, healthier-looking gums, and reduced inflammation. Remember, every pet is unique, so results may vary.
While 1-TDC significantly improves oral health, we recommend it as part of a comprehensive dental care routine, not a replacement for brushing or professional cleanings.
Think of it as a powerful supplement that works from the inside out to support gum health and reduce inflammation, while traditional dental care addresses external plaque and tartar buildup.
Yes! Bad breath is often a symptom of gum inflammation and periodontal disease. Since 1-TDC reduces inflammation at the source, many pet parents notice fresher breath within the first few weeks.
Unlike breath mints that just mask odor, 1-TDC addresses the underlying cause — healthier gums naturally lead to fresher breath.
Yes! 1-TDC is safe for pets of all ages. In fact, many of our success stories come from senior pets experiencing age-related periodontal issues.
Senior pets often see some of the most dramatic improvements because they're dealing with the exact conditions 1-TDC addresses. As always, consult with your veterinarian if you have specific health concerns.
1-TDC is a naturally-derived compound with an excellent safety profile. Side effects are extremely rare.
As with any supplement, we recommend consulting your veterinarian if you have concerns, especially if your pet has existing health conditions or is taking other medications.
1-TDC has no known drug interactions, making it safe to use alongside most medications. However, we always recommend consulting with your veterinarian about your pet's specific medication regimen.
Your vet knows your pet's complete health history and can provide personalized guidance for combining 1-TDC with any current treatments.
Yes. 1-TDC capsules are designed to be safely ingested. Whether your pet swallows the capsule whole or you squeeze the contents onto their gums or food, it's completely safe either way.
Most pet parents choose 1-TDC for oral health — but many notice easier movement and more playful energy as a bonus. In a customer survey, 83% of pet parents reported mobility improvements, typically within 1–2 months.

My son's dog is running like a dog half his age. He'll be 11 soon and you'd never know it! Thank you 1TDC!
1-TDC Oral Health + Mobility Support for Dogs
Store owner replied: That is awesome!! Thank you for sharing. We would love to see a video or picture of him running and playing like a youngster.
I’ve used the supplement for my dog for almost a decade. She’s now 14 and most people think she’s much much younger than her age. She retired from agility at 11 and parkour at 13. Never had any injuries or joint issues. I credit 1-TDC Oral Health for contributing to my girl’s longevity and joint health. Sadly it’s gotten harder and harder to source the product.

I have used this product for years. I have not noticed their teeth getting better but they definitely haven't gotten worse. Pete is 16 and his mobility has improved especially during the winter months. He is a little stiff when he first gets up in the morning but like me, he walks it off within a few steps. I highly recommend this product and have to many others.

Great orange and mobility support. My kitty who had bad, painful mucositis responded well where she didn't need any pain medications. My dog who had patellar injury maintained mobility until his surgery and continues with the supplement. Definitely a great supplement for our family pets.

I was getting ready to put my 14 1/2 year-old dog on some type of prescription pain meds as she appeared to be in pain and stiff all the time.. However, the works so well tdc1 saved her from that. Her mobility is good and she limps so much less. She doesn’t appear to be in pain anymore. Also no side effects noted. She is happy and sassy as ever. A+ recommended.

Store owner replied: Thank you so much for sharing and we are glad that she is feeling better - more mobile. Thanks you for the picture, she is very cute.
I bought these after a vet recommended them to help with my pug's teeth and overall oral health, and the joint health was a bonus (she just got double TPLO). In general, I feel it's hard to say a supplement is really working for its intended purposes, especially for a dog. However, we did have a vet visit the other day, and she said the teeth/mouth were looking good. Our next dental is not for a few months yet. We have also added other measures, too - brushing more, etc. My dog really likes the supplement, and it doesn't seem to be hurting her, so I plan to continue giving it to her. It seems like a good product and vet-recommended. The outside of the supplement is too hard for her to chew, so we throw that part away. This could be because she doesn't have many teeth left to chew it; it's kind of rubbery, and I feel it's a choking hazard for her. Pug-approved!
1-TDC Oral Health + Mobility Support for Dogs
Store owner replied: Thank you for sharing your experience. Great news that your vet sees her oral health results. It is ok that she does not eat the capsule itself, it is edible, but not necessary to give it to your pet. Please add a picture of her, we would love to see her.

I do not know if it works or not. I hope it makes my elderly doggie feel a bit better. they keep sending me emails to review the product. this is all I can say. I will keep giving it to her in case it helps. she won't eat it in the pill casing so I squeeze it on her food and mix it up. She does not like the taste.

I thought this was something that my dog eats. Not that I would have to be put on daily in his mouth. I tried it once and he practically bit my hand off!
Unfortunately this formula was not good for my boy’s tummy. He got severe diarrhea and I had to stop using the product.
1-TDC Oral Health + Mobility Support for Dogs
Store owner replied: We are sorry to hear that it did not work for him. Sometimes if a dog can be sensitive, you can do a very slow introduction. If that does not work, you can also apply it topically to the pinna of the ear and leave it for up to 10 minutes and then gently wipe it off. You will still receive the benefits without it going through the gut. Please reach out with any questions.
Recommended by a friend in dog agility, this supplement works wonders for my 11-year-old pup. We don't do intense sports, but it drastically improves his daily mobility. It has made a massive difference in both of our lives! Seeing him more comfortable means the world!

Store owner replied: Thank you for sharing your experience and we are so happy that your 11 year old is doing so well with 1-TDC. We would love for you to add a picture of him!
So far... so good. His teeth are looking good. He seems to enjoy taking them. The video showed twisting off that small top and squirting it onto his teeth on both sides and then giving the remainder for him to chew. I do not have the strength in my fingers to twist off something so small, so to nip it off with scissors. He seems to enjoy the taste and enjoys eating the remainder. He even begs for that tiny piece that I cut off. It has only been 3-4 weeks, so I have not yet noticed improvement in his ability to jump up on the bed yet, but he does have much more energy and he has gotten his morning zommies back. So far I am well pleased.

TerrA at her best!
In her middle years, my small dog lost quite a few teeth due to accumulated plaque and tartar and periodontal disease. She absolutely hated having her teeth brushed. Her mouth was painful. Since using this product, her gums and teeth are clean and healthy. Great product!
A combination of 1-TDC and dental chews has done wonders for my dog's teeth.
