Your tracking number is included in the dispatch confirmation email sent after your order leaves our fulfilment facility. Check your inbox, spam folder and promotions folder.

You can enter the number on our Track Order page.

Contact us as soon as possible at support@glyntho.com . We will try to help before the order enters fulfilment, but changes and cancellations cannot be guaranteed after processing has begun.

Check the spam, junk and promotions folders connected to the email address used during checkout.

If you still cannot find it, email customer care with your full name, delivery address and the approximate time of purchase.

Orders are normally processed within 1–3 business days, excluding weekends and public holidays.

Processing may take longer during major promotions, product launches or unusually busy periods.

Delivery estimates begin after dispatch:

• United States: approximately 4–10 business days.
• International destinations: approximately 7–14 business days.

These are estimates and may be affected by customs, weather, carrier disruption or public holidays.

Check around your property, designated safe place, reception, parcel locker and with neighbours or building management.

Allow up to 48 hours because some carriers mark parcels as delivered shortly before completing delivery. Contact the carrier and then email us if the parcel remains missing.

International orders may be subject to customs duties, VAT, import taxes or handling charges imposed by the destination country.

Unless clearly stated at checkout, these charges are the customer’s responsibility.

Eligible return requests should be submitted within 30 calendar days of confirmed delivery.

Review the complete Refund and Returns Policy before sending anything back.

Opened or used brush heads cannot normally be returned because they are personal oral-care items.

Brush heads received damaged, defective or incorrect remain eligible for assessment and possible replacement.

Email support@glyntho.com before returning the product.

Please include:

• Your full name.
• Your order number.
• The reason for the return.
• Photographs or video if the product is damaged or defective.

Once a return is received, allow approximately 3–5 business days for inspection.

Approved refunds are normally submitted within 5–10 business days. Your bank or payment provider may need additional time to display the funds.

1. Attach the brush head securely.
2. Apply a small amount of toothpaste.
3. Place the brush head against your teeth.
4. Press the circular power button.
5. Guide the brush slowly along the teeth and gumline without pressing too hard.
6. Switch it off, rinse the head and allow it to dry.

Follow the product instructions supplied with your order.

The cylindrical roller head has fine bristles arranged around the head, creating broader contact as you guide it along your teeth.

Use controlled movements and avoid pressing aggressively against the gums.

Rinse the brush head after use and remove any toothpaste residue. Allow the product to dry in a clean, ventilated area.

Do not use harsh chemicals, abrasive cleaners or unsuitable heat. Follow the care instructions supplied with the product.

Replace the head when the bristles become worn, frayed, damaged or less effective.

Replacement timing may vary depending on frequency of use and brushing pressure.

Use gentle pressure and follow the supplied instructions. Individual needs vary.

Speak with a qualified dentist before use if you experience ongoing pain, swelling, bleeding, significant sensitivity or have recently undergone dental treatment.
