Part of our Synadentix overview. Last checked October 28, 2026.
Synadentix amazon and Walmart searches lead to a simple answer: we did not check either store, and the vendor says "Synadentix can be found only on this page"[1][2]. Orders placed through the vendor site go to the BuyGoods checkout and carry a 90-day refund counted from delivery[3]. A bottle from any other seller may not qualify for that refund, so the seller matters as much as the price.
Where should you buy Synadentix?
Buy Synadentix from the vendor site, thesynadentix.com, if you want the 90-day refund, because the vendor's refund process asks for an order id and packing slip from its own orders[3]. Checkout runs on BuyGoods, the retailer that also handles order support through its order lookup page[6].
Prices on the vendor page, checked October 28, 2026, are $158 for 2 bottles, $207 for 3 and $294 for 6[7]. There is no single-bottle order. The vendor FAQ says each order is a one-time charge with no autoship[2]. After checkout you may see offers of 3, 6 or 12 more bottles at $29 each; decline any you did not plan to buy. Our Synadentix price and coupon guide breaks those totals down, including shipping.
Shoppers outside the US can find shipping notes in our guide for the UK, Canada and Australia.
Can you buy Synadentix on Amazon or Walmart?
We cannot say whether Synadentix is on Amazon or Walmart, because we did not search either marketplace for this guide. That stays NOT checked. Here is what we did check on October 28, 2026:
| Where | Checked? | What we found | Vendor refund applies? |
|---|---|---|---|
| thesynadentix.com via BuyGoods | Yes | Prices, label, refund terms | Yes, 90 days from delivery |
| A third-party sales page (not linked) | Yes | Same 10 ingredient names, "Today's Price: $49/each", its own 90-day guarantee | Not stated by the vendor |
| Amazon | NOT checked | No data | Not stated by the vendor |
| Walmart | NOT checked | No data | Not stated by the vendor |
| Pharmacies and stores | NOT checked | No data | Not stated by the vendor |
The vendor's "only on this page" line conflicts with that third-party listing[4]. We do not know who runs that site.
Why does the seller matter?
The seller matters because it decides whether the bottle is genuine, how it was stored, whether the refund applies and which formula you get. A lower price elsewhere means little if any of those fail.
Authenticity
The vendor publishes its label image: 30 soft chewable tablets, a 400 mg proprietary blend and a distributor line reading Synadentix, 285 Northeast Ave, Tallmadge, OH 44278[5]. A bottle that does not match that label is a warning sign.
Storage
The blend includes enzymes such as lysozyme and lactoperoxidase. The label does not give storage limits, and a reseller's storage is unknown. The tablets contain xylitol, which is toxic to dogs, so keep any bottle out of a pet's reach.
Refund eligibility
The refund needs the packing slip and an order id, and every bottle goes back to Tallmadge, Ohio[3].
Current formula
Resellers may hold older stock, and a listing photo may show a different label than the bottle you receive. The ingredient list on the vendor's references page is the one to compare against. Our chewable tablet guide describes the format.
How do you verify a seller before paying?
Verify a Synadentix seller with four checks before you enter card details. Each takes under a minute.
Check the checkout address
The vendor's order page sits on buygoods.com. A different payment page means a different seller.
Check the price
Vendor prices run $49 to $79 a bottle, checked October 28, 2026. A far lower price, or a single bottle, does not match the vendor offer.
Check the refund terms
Look for 90 days from delivery and the Tallmadge, Ohio returns address.
Check the label photo
Compare the bottle with the vendor's own image below.
Red flags with unknown sellers
Unknown sellers show a few clear red flags. The vendor sells no single bottle and lists a US returns address, so a listing that breaks either pattern is not a vendor order. Walk away if you see any of these:
- A price well below $49 a bottle, or a single bottle when the vendor sells none
- No returns address, or one outside the US
- A label without the 400 mg proprietary blend or the Tallmadge, Ohio distributor line
- Promises of overnight results, or claims the vendor itself does not make
- A broken or missing seal
- Payment by gift card, wire or crypto
- A storefront with no order support contact
What should you save after ordering?
Save four records after ordering, since the refund depends on dates and paperwork. Keep the order receipt email with your order id. Note how the charge appears on your card statement so you can match it later; with no upsells accepted, you should see one charge. Keep the carrier tracking page, because the 90-day window starts on the delivery date. Photograph the bottle label and any batch or lot number, and keep the packing slip, which the refund requires[3]. For order questions, BuyGoods runs an order lookup page[6].
Buyer takeaway
We did not check Amazon or Walmart, so we cannot confirm listings there. The vendor sells through thesynadentix.com with a BuyGoods checkout, and only those orders clearly fall under its 90-day refund. Whatever you buy, keep brushing, flossing and seeing your dentist, and read whether Synadentix is legit before you order.

Frequently asked questions
Is Synadentix sold on Amazon?
We did not check Amazon, so we cannot confirm a listing. The vendor says Synadentix is found only on its own page, and its 90-day refund needs an order id and packing slip from a vendor order placed through BuyGoods.
Can I buy Synadentix at Walmart?
Walmart was not checked for this guide. The vendor sells Synadentix through thesynadentix.com with checkout on BuyGoods, from $158 for 2 bottles to $294 for 6, checked October 28, 2026. Compare any other listing with those terms.
Is Synadentix sold in stores like CVS or Walgreens?
We did not check pharmacies or stores. The vendor sells online through its own site and BuyGoods, and says the product is found only on its page. A store bottle may not fall under the vendor refund policy.
Are third-party Synadentix sales pages the vendor site?
We found at least one third-party sales page and do not know who runs it. It is a single-page site listing the same 10 ingredient names and a 90-day guarantee. The vendor domain is thesynadentix.com, with checkout on BuyGoods and returns to Tallmadge, Ohio.
Does the Synadentix refund cover other sellers?
The vendor does not say so. Its refund steps ask for an order id, the packing slip and every bottle mailed to 285 Northeast Ave, Tallmadge, OH 44278 within 90 days of delivery, which fits orders placed through its own checkout.
