As consumers around the world become increasingly focused on preventive dental care and daily oral hygiene, electric toothbrushes and water flossers are becoming important parts of modern oral care routines. Behind this growing market is a continuous demand for better cleaning performance, smarter functions, ergonomic designs, reliable manufacturing and internationally compliant products.

Jiangsu Longde Oral Care Company Limited is responding to these changing market requirements through more than three decades of experience in oral care research, manufacturing and product development. Founded in 1988 in Yangzhou, Jiangsu, China, Longde has developed from an established toothbrush manufacturer into a National High-tech Enterprise specializing in manual toothbrushes, electric toothbrushes, water flossers and other oral care products.

With a 60,000-square-meter manufacturing area and approximately 300 professional employees, Longde has established an integrated production and development system designed to support customers from product concept and engineering development through manufacturing and delivery.

Growing Demand for Advanced Electric Oral Care Products

The development of electric toothbrushes and water flossers reflects a broader shift in consumer expectations. Traditional oral care remains important, but consumers increasingly seek products that can provide more convenient, efficient and personalized cleaning experiences.

Electric toothbrushes can incorporate technologies such as high-frequency motor systems, multiple brushing modes, smart timing functions, rechargeable battery systems and interchangeable brush heads. Water flossers, meanwhile, use controlled water pressure to help clean between teeth and along the gumline, providing an alternative or complement to traditional flossing methods.

As these categories continue to evolve, manufacturers need to combine consumer-oriented design with reliable engineering. Longde has therefore continued to allocate a fixed annual budget to its R&D center for new functions, new technologies and specialized research projects.

The company's R&D organization includes more than 45 researchers and has accumulated more than 300 patents and 11 software copyrights. This ongoing investment allows Longde to explore new product structures, functional improvements and manufacturing technologies while supporting customers with customized OEM and ODM solutions.

Research and Development as a Core Manufacturing Capability

For Longde, product development is closely connected with manufacturing. Instead of treating R&D, tooling and production as independent processes, the company has developed a one-stop manufacturing model.

Its facilities include a tooling center, automatic production lines and professional automatic toothbrush head bristle planting equipment. These production capabilities help maintain consistency across different product models and support large-scale manufacturing requirements.

The integration of engineering and manufacturing also provides advantages when developing customized electric toothbrushes and water flossers. Customers can work with Longde on product appearance, functional configurations, packaging requirements, brush head specifications and other product details according to their target markets.

This approach is particularly valuable for international brands that need to launch oral care products under their own brands while maintaining consistent quality and production efficiency.

Supporting the Development of Electric Toothbrush Technology

Electric toothbrush manufacturing requires coordination across multiple components, including motors, batteries, electronic control systems, brush heads, charging structures, housings and user interfaces.

Longde has continued to invest in research  into new functions and technologies to meet different market requirements. The company's experience in oral care manufacturing allows its development teams to consider both product performance and manufacturing feasibility during the design process.

As a director unit of the China Household Electrical Appliance Association, Longde is also one of the main formulators of electric toothbrush and water flosser standards. Participation in industry standard development gives the company practical insight  into technical requirements and helps strengthen its understanding of product quality and industry trends.

For customers developing new electric toothbrush programs, this combination of industry experience, engineering capability and manufacturing resources can help shorten the path from concept to mass production.

Water Flosser Manufacturing for Modern Oral Care

Water flossers have also become an important category within the modern oral care market. Their combination of water pressure technology, compact product design and convenient operation has made them increasingly attractive to consumers looking for additional interdental cleaning solutions.

Developing a reliable water flosser requires careful attention to water flow, pressure control, pump performance, battery systems, water tanks, sealing structures and product ergonomics.

Longde's experience in water flosser development allows the company to support customers across these different manufacturing requirements. Its product development capabilities can be integrated with tooling, automated production and quality control processes to provide a complete manufacturing solution.

This is especially important for private-label and OEM customers that need products adapted to different markets. Longde can support product development based on customer requirements while maintaining attention to manufacturing efficiency and quality consistency.

Quality Systems Designed for International Markets

Global oral care brands require suppliers that can meet increasingly strict quality and compliance expectations. Longde has established a quality management and manufacturing system designed to serve international customers.

The company has obtained certifications and approvals including ISO 9001, ISO 13485, BSCI, FSC and GMP-related qualifications, while its products have received certifications such as FCC, CE, CB and ETL, with products also registered on FDA-related systems  applicable.

Longde also operates a GMP clean room, while its workshop has undergone BSCI and FSC audits. These systems provide customers with additional confidence when sourcing electric toothbrushes, water flossers and other oral care products for international markets.

Quality management is incorporated throughout the manufacturing process rather than being limited to final inspection. This helps the company maintain greater control over materials, production processes, product assembly and delivery.

Digital Manufacturing Management for Better Production Control

Modern oral care manufacturing requires more than advanced machinery. Efficient production management is equally important, particularly for large OEM and ODM orders.

Longde uses an advanced SAP manufacturing management system to control the manufacturing process from customer order and production scheduling to material supply, manufacturing operations and delivery management.

By connecting these stages through an integrated management system, the company can improve production visibility and coordination. This is particularly important when customers require multiple models, customized configurations or scheduled deliveries.

Combined with automated production equipment and experienced production teams, digital manufacturing management helps Longde provide high-quality and cost-efficient manufacturing services while supporting on-time delivery.

One-Stop OEM and ODM Oral Care Solutions

International brands often need more than a standard catalog product. They may require customized appearance, packaging, product functions, brush head designs, colors or other specifications.

Longde's one-stop manufacturing capability enables customers to work with a single experienced supplier across multiple stages of product development and production.

From tooling and product engineering to automated manufacturing and delivery management, the company can coordinate different production processes under one integrated system.

This capability is particularly relevant to brands looking to expand their electric toothbrush and water flosser portfolios. Instead of developing every component independently, customers can cooperate with a manufacturer that already has extensive experience in oral care product development.

Building the Next Generation of Oral Care Products

The future of oral care manufacturing will continue to be shaped by technology, consumer expectations and international market requirements. Electric toothbrushes and water flossers are likely to become increasingly diversified as brands seek better functionality, more convenient user experiences and differentiated product designs.

Longde is continuing to invest in research, manufacturing technology and product development to respond to these changes.

With more than 30 years of oral care manufacturing experience, a 60,000-square-meter production base, more than 45 researchers, hundreds of patents and extensive certification capabilities, Longde provides an established foundation for developing and manufacturing modern oral care products.

The company's experience serving world-famous brands and dental institutions further demonstrates its ability to meet demanding product and manufacturing requirements.

As the oral care industry moves toward more technologically advanced products, Jiangsu Longde Oral Care Company Limited remains focused on combining research, engineering, manufacturing and quality management to help global customers bring reliable electric toothbrushes, water flossers and other oral care products to market.

For brands seeking a long-term OEM and ODM manufacturing partner, Longde offers an integrated approach built on professional R&D, advanced production equipment, digital manufacturing management and more than three decades of oral care expertise.
