Part of our Synadentix overview. Last checked October 28, 2026.
Synadentix price coupon searches end at the vendor's bundle prices: we found no coupon code, and the lowest price is $49 a bottle in the 6-bottle order, $294 in total[2]. The smallest order is 2 bottles for $158. All figures come from the vendor page and its price file, checked October 28, 2026, because the BuyGoods checkout totals load by script and we could not capture them.
How much does Synadentix cost?
Synadentix costs $79, $69 or $49 a bottle depending on the order size, checked October 28, 2026. The vendor sells three bundles: 2 bottles for $158, 3 bottles ("2 + 1") for $207 and 6 bottles ("3 + 3") for $294[1][2]. There is no single-bottle option.
Each bottle holds 30 soft chewable tablets. At 1 tablet a day a bottle lasts 30 days; at the label maximum of 2 a day it lasts 15[7]. The vendor also shows a "was" price of $179 a bottle, which we could not link to any real sale. Payment runs through BuyGoods, so confirm the final figure on the payment page before you pay.
Synadentix price table
The 6-bottle order is the lowest cost per bottle and per day; the 2-bottle order is the smallest outlay. Figures are from the vendor page and price file, checked October 28, 2026.
| Package | Per bottle | Total | US shipping | Cost per day (1 tablet) | Source, date |
|---|---|---|---|---|---|
| 2 bottles | $79 | $158 | $9.99 in the price grid | $2.63, or $2.80 with shipping | Vendor page, checked October 28, 2026 |
| 3 bottles (2 + 1) | $69 | $207 | Free | $2.30 | Vendor page, checked October 28, 2026 |
| 6 bottles (3 + 3) | $49 | $294 | Free, plus 3 bonus ebooks | $1.63 | Vendor page, checked October 28, 2026 |
At 2 tablets a day the daily cost doubles: about $5.27 (2 bottles), $4.60 (3 bottles) and $3.27 (6 bottles).
Are there real Synadentix coupons or discounts?
No Synadentix coupon code appears on the vendor page, sales FAQ or price file we read on October 28, 2026[2]. The discount is built into the bundles: the per-bottle price drops from $79 to $49 as the order grows.
Searches also pair Synadentix with third-party sites listing coupons. We did not check those sites and cannot confirm any code they list. One third-party sales page shows "Regular Price: $129/each, Today's Price: $49/each"[6], the same $49 as the vendor's 6-bottle order.
A second set of prices appears only after checkout: upsells of 3, 6 or 12 more bottles at $29 each ($87, $174 or $348), and downsells of 2 for $58, 4 for $116 or 6 for $174[2]. These are add-ons to an existing order, not coupons. Decline any you did not plan for.
Which package is the best value?
The 6-bottle order is the best value per bottle at $49, but the 2-bottle order risks the least money if Synadentix does not suit you. The per-bottle saving is $30 between the smallest and largest order.
| Order | Supply at 1 a day | Supply at 2 a day | Money at risk |
|---|---|---|---|
| 2 bottles | 60 days | 30 days | $158 plus shipping |
| 3 bottles | 90 days | 45 days | $207 |
| 6 bottles | 180 days | 90 days | $294 |
The refund window is 90 days from delivery, so a 6-bottle buyer at 1 tablet a day still has about 3 bottles left when it closes. Every bottle goes back by mail at your cost[4]. Read whether Synadentix works before you pick a size.
Is it a subscription or a one-time purchase?
Synadentix is a one-time purchase. The vendor FAQ says there is no autoship and no recurring charge[5]. Your card is charged once for the bundle you pick, plus any upsell you accept after checkout. Check the order summary and receipt email: an accepted $29-a-bottle upsell is a separate charge. BuyGoods, the retailer, handles order support.
How does the Synadentix refund work?
Synadentix refunds run 90 days from the delivery date, and you must mail back every bottle at your own cost. The sales page promises "we'll refund every single cent"[1]. The refunds page sets these steps[4]:
- Check your delivery date on the carrier tracking page.
- Email support with "Refund Request" in the subject.
- Mail all bottles, empty or not, with the packing slip and a note (full name, email, order id) to 285 Northeast Ave, Tallmadge, OH 44278.
- Wait 5 to 10 days for the refund to show on your card.
What is not refunded: return postage. The page states "we do not support the return shipping costs." The contact FAQ says "return what you haven't used", which conflicts with the all-bottles rule[5]. The Synadentix complaints guide covers the other refund issues.
How shipping changes the real price
Shipping adds up to $9.99 to the 2-bottle order and nothing to the larger ones. The shipping policy page says US shipping is free on all orders, but the price grid adds $9.99 to 2 bottles[3][2]. Real totals in the US: $158 to $167.99 for 2 bottles, $207 for 3 and $294 for 6. Return postage on a refund adds your own cost on top.
Buyer takeaway
No coupon beats the vendor's own bundles: $79, $69 or $49 a bottle, checked October 28, 2026. Pick the size you would be comfortable mailing back, decline upsells you did not plan for, and save your delivery date. Tablets do not replace brushing, flossing or dental visits.
