1. Choose a Kids’ or Adult Product Range
A U-shaped electric toothbrush combines a powered handle with a mouthpiece-style brush head. Relish develops kids’ and adult ranges with customized silicone mouthpieces, sonic functions, handles, branding and packaging. Start with the intended user and the role of the product in your retail range.
For a children’s range, character handles, colors, voice guidance and oral care education can help create an engaging presentation. For adults, a refined handle, clear controls and a coordinated storage or charging setup offer a different design direction. The mouthpiece and complete product should be reviewed for the users you intend to serve.
Set a clear product direction| Range | What to include in the brief |
|---|
| Kids’ designs | Target age group, mouthpiece fit, character concept, grip, voice or educational features and supervision information. |
|---|
| Adult designs | Mouthpiece dimensions, handle finish, controls, selected functions and retail positioning. |
|---|
| Private mold | Drawings or reference samples, intended geometry, material, development stages and sample approvals. |
|---|
Define the sales channel and complete retail set early. A device, replacement-mouthpiece pack and gift set may share a brand identity while requiring their own contents, artwork and SKU references.
2. Compare Mouthpiece Fit, Materials & Bristle Layout
The U-shaped mouthpiece is central to product selection. Review curvature, width, length, bristle layout, softness and the connection to the handle together. A target age range helps describe the audience, while dimensions and samples define the actual fit being developed.
Review the Silicone Structure on a Sample
Relish supports food-grade silicone mouthpieces and multi-layer bristle layouts, including five-layer options for applicable designs. Compare the contact area, bristle length, edge finish and flexibility on the complete assembled device. Record the selected mouthpiece reference and changes before approving tooling or production.
Food-grade ABS or PC housing options and soft, drop-resistant silicone components can be reviewed for the selected model. Identify the housing and mouthpiece materials separately. Review grip, surface finish and the way the handle supports the head, rather than choosing the product only by its appearance.
Plan Compatible Replacement Mouthpieces
Choose replacement heads together with the handle. Agree the attachment, mouthpiece dimensions and reference for each size or variant. Keep those identifiers on the specification and replacement packaging so later orders use the same compatible configuration.
For a new shape or private mold, use a drawing or physical reference to keep the fit discussion precise. Review the mouthpiece and handle as one product before finalizing the retail artwork.
3. Specify Modes, Controls, Charging & Light Features
Compare the working configuration that your brand intends to sell. The motor, silicone mouthpiece, controls, timer, charging and accessories should follow one product specification. Strong or gentle mode names alone do not describe the full function; record the selected settings and how the customer operates them.
Prepare a complete functional brief| Planning area | What to agree |
|---|
| Motor and modes | Motor specification, intensity settings, mode sequence and controls for the selected design. |
|---|
| Timer and guidance | Operating cycle, indicators, any voice-guidance content and the intended instruction language. |
|---|
| Power and charging | Battery capacity, charging method and time, base, cable and included accessories. |
|---|
| Optional light features | Selected LED function or UV-equipped base, settings, instructions and corresponding test information. |
|---|
Review Optional Features as Part of the Product
LED whitening or other light features can be integrated into suitable designs. Specify the selected light configuration, control and operating requirements alongside the core brushing functions. Charging-base features should have their own agreed configuration and instructions, including the relevant test information for any stated function.
For the power setup, check the actual base and accessories with the device. Match waterproof and care information to the chosen model, and make the complete box contents clear in the quotation and retail pack.
4. Develop Your Private Label Design & Packaging
Bring your concept, drawings or reference samples to Relish’s product team. Our own SMT, injection molding and silicone molding capabilities support the handle, mouthpiece and electronics, while the in-house design team coordinates the product’s branded presentation.
Choose the Development Route
Use an existing model when its format and functions fit your range, then define logo, colors, finish and packaging. For a new character, handle, mouthpiece or functional requirement, agree the design and tooling scope before setting the sample and production schedule.
Children’s designs can combine a recognizable character with voice guidance and clear parent-facing instructions. Adult ranges can emphasize the finish, grip, controls and coordinated accessories. Carry the same visual identity through the handle, box and any replacement-mouthpiece packs.
Build the Box Around the Finished Set
Plan the handle, mouthpiece, base or cable, instructions and other agreed accessories together. Packaging options include custom printing, finishes, die-cut windows, inserts and gift boxes. Review pack protection, the contents list and unboxing on an assembled sample.
Keep the artwork version, model and mouthpiece references, required languages and pack quantity in the approval record. This helps the product, instructions and retail presentation follow the same design.
5. Approve Samples, Quality & Order Planning
Use the sample stage to assess the mouthpiece, controls, motor settings, handle finish, charging and retail set together. Discuss changes against the written brief, then approve one reference sample and specification for production, inspection and future orders.
Sample and production approval checklist| Review area | What to retain |
|---|
| Device and mouthpiece | Model, dimensions, materials, bristle layout, fit and head-to-handle connection. |
|---|
| Functions and power | Motor settings, controls, cycle, charging specification, accessories and optional functions. |
|---|
| Brand and packaging | Colors, logo, artwork version, complete kit list and user instructions. |
|---|
| Quality and shipment | Inspection requirements, quality report, relevant documents, quantities and destination. |
|---|
Custom OEM/ODM orders start from 1,000 units, with flexibility according to the order. Wholesale orders for available stock products start at 50 units. Include the target market, intended users, design, quantity, functions and packaging in your inquiry; identify new tooling or development as a separate project scope.
Match the Schedule to the Project
Selected in-stock models can be branded and shipped in 7 working days. For routine projects, our published OEM guide lists samples at approximately 3–7 days and mass production usually at 25–35 days after final sample approval, depending on volume and material availability. Private molds, functional development and additional packaging work need their own agreed stages.
Relish’s existing certificates, ISO quality systems, 23-step quality control and pre-shipment inspection support supplier assessment. Review the relevant product and factory documents alongside the selected model and market. Keep the approved specification, quality requirements and reporting details with the order.
For repeat orders, reference the original handle and mouthpiece, settings, colors and artwork. State changes explicitly so the next batch and replacement components follow the configuration your brand approved.
6. Prepare Use, Cleaning & Children’s Guidance
Clear instructions help customers understand the selected device. Describe mouthpiece placement, pressure and any movement required by the design, then explain the mode controls, operating cycle and charging steps. Review the wording with the actual working sample and intended user group.
Keep Daily Care Guidance Clear
General NHS oral hygiene guidance recommends fluoride toothpaste and brushing twice daily for about two minutes. A device’s programmed cycle should not be presented as proof that every tooth surface has been cleaned. Explain the technique and care routine appropriate to the chosen product.
Help Parents Understand the Children’s Version
Character designs and voice prompts can support a friendly brushing routine. Packaging should also identify the intended age or fit range, explain supervision and show how the mouthpiece is positioned. NHS children’s guidance emphasizes adult help and supervision while children develop their brushing skills.
For individual fit concerns, sensitive mouths, dental appliances or additional care needs, instructions can direct users to a dental professional. Keep the intended audience and product guidance specific to the mouthpiece and configuration being supplied.
Explain Cleaning, Storage and Replacement
Identify which parts can be detached or rinsed, how the handle and mouthpiece should be cleaned and dried, and how to protect the power connection. Match immersion, charging-base and cleaning information to the chosen model’s specification. A UV-equipped base should follow its own operating instructions.
Describe the condition checks and mouthpiece replacement information for the selected design. Keep the compatible head reference easy to find on refill packaging, and align the device instructions, retail box and replacement packs so customers can identify the correct parts.
Build your private label U-shaped toothbrush range. Send the intended users, mouthpiece requirements, functions, design direction, quantity and packaging brief.
