Learn the safest ways to clean and sterilize silicone teethers, including boiling, dishwasher, and steam methods, to keep your baby's teething toys hygienic.
Teething is a challenging phase for both babies and parents. As soon as those first little teeth start pushing through, your baby will want to chew on everything in sight. Silicone teethers are a lifesaver during this time, offering a safe, soothing surface for sore gums. But with all that chewing and drooling, keeping them clean is essential to prevent the buildup of germs and bacteria.
In this guide, we'll walk you through the safest and most effective ways to clean and sterilize silicone teethers. From quick daily washes to deep sterilization methods, you'll learn how to keep your baby's teethers hygienic without damaging the silicone. We'll also cover what to avoid, how to extend the life of your teethers, and when to replace them.
Why Proper Teether Hygiene Matters
Babies have developing immune systems, making them more susceptible to infections. When a teether is dropped on the floor, tossed in a diaper bag, or handled by little hands, it can pick up dirt, bacteria, and other pathogens. Since teethers spend a lot of time in your baby's mouth, any germs on the surface can easily be ingested.
Regular cleaning and sterilization help reduce the risk of illness and keep the teether safe for repeated use. It's not just about visible dirt; even clear silicone can harbor microscopic bacteria. Establishing a routine for cleaning and sterilizing your baby's teethers is a simple yet crucial step in maintaining their overall health.
Moreover, proper care can extend the lifespan of your teethers. Silicone is durable, but harsh cleaning methods or exposure to high heat can cause it to degrade, lose its shape, or become sticky. By following the right techniques, you can keep your teethers in great condition for the entire teething period.
- Clean teethers after every use, especially if they've been dropped or handled outdoors.
- Sterilize teethers at least once a day, or more often if your baby is sick.
- Always inspect teethers for signs of wear and tear before cleaning.
Daily Cleaning Routine for Silicone Teethers
For everyday cleaning, warm soapy water is your best friend. Fill a clean basin or sink with warm water and add a mild dish soap. Submerge the teether and gently scrub it with a soft sponge or cloth, paying attention to any textured areas where dirt can hide. Rinse thoroughly under running water to remove all soap residue, then air dry on a clean towel.
You can also use a dedicated bottle brush or a soft toothbrush for a more thorough clean, especially for teethers with intricate shapes or small crevices. Avoid using abrasive scrubbers or harsh cleaning agents, as they can scratch the silicone surface, creating tiny grooves where bacteria can thrive.
If you're on the go, a quick rinse with clean water and a wipe with a baby-safe wipe can suffice until you can do a proper wash. However, make sure to wash the teether with soap and water as soon as possible, especially if it has been in contact with dirt or other contaminants.
- Use a designated cleaning brush for teethers to avoid cross-contamination.
- Dry teethers completely before storing them to prevent mold growth.
- Avoid using bleach or other harsh chemicals on silicone teethers.
Sterilization Methods: Boiling, Steaming, and Dishwasher
Sterilization goes a step beyond cleaning by killing germs and bacteria. The most common methods for silicone teethers are boiling, steaming, and using a dishwasher. Each has its pros and cons, so you can choose the one that fits your lifestyle.
Boiling is a tried-and-true method. Fill a pot with water and bring it to a rolling boil. Place the teether in the boiling water and let it boil for 2-3 minutes. Use tongs to remove it and let it cool completely before giving it to your baby. Boiling is effective, but be cautious: prolonged boiling can damage silicone over time, so keep the time short.
Steaming is another gentle option. You can use an electric steam sterilizer designed for baby bottles, or simply place the teether in a steamer basket over boiling water for 5 minutes. This method is less harsh than boiling and is effective at killing germs.
Many silicone teethers are dishwasher safe. If yours is, place it on the top rack of your dishwasher and run a normal cycle with a gentle detergent. The high water temperature and steam will sterilize the teether. However, avoid using the heated dry cycle, as excessive heat can warp the silicone. Always check the manufacturer's instructions to confirm dishwasher safety.
- Always let teethers cool completely after sterilization before giving them to your baby.
- If using a dishwasher, place teethers in a mesh bag to prevent them from moving around and getting damaged.
- Do not use microwave sterilizers unless the manufacturer explicitly states they are safe.
What to Avoid When Cleaning Silicone Teethers
While silicone is a durable material, it has its limits. Avoid using abrasive cleaners, scouring pads, or harsh chemical disinfectants, as they can damage the surface and leave residues that are unsafe for your baby. Similarly, do not use UV sterilizers unless the teether is specifically marked as UV-safe.
Extreme temperatures can also harm silicone. Do not put silicone teethers in the freezer unless the product is designed for it, as freezing can make them brittle. Likewise, avoid leaving them in direct sunlight for extended periods, as UV rays can degrade the material over time.
Another common mistake is using the same cleaning cloth or sponge for teethers and other household items. This can transfer bacteria and cross-contaminate. Dedicate a specific brush or cloth for baby items and wash it regularly.
- Never use bleach, alcohol, or other harsh disinfectants on silicone teethers.
- Avoid using a microwave to sterilize silicone teethers unless the product is explicitly labeled as microwave-safe.
- Do not use a dishwasher if the teether has any metal parts, as they may rust or damage the dishwasher.
How Often Should You Clean and Sterilize Teethers?
The frequency of cleaning depends on how often your baby uses the teether and the environment it's exposed to. As a general rule, wash the teether with soap and water after every use. If the teether falls on the floor or is handled by other children, clean it immediately.
Sterilization should be done at least once a day, especially for infants under 6 months old. If your baby is sick or has a weakened immune system, you may want to sterilize more frequently. Some parents prefer to have multiple teethers on hand and rotate them, so each one gets a thorough cleaning before being used again.
It's also a good idea to inspect teethers regularly for any signs of wear, such as cracks, tears, or sticky spots. If you notice any damage, replace the teether immediately to prevent pieces from breaking off and becoming a choking hazard.
- Keep a few spare teethers in rotation to ensure each one is properly cleaned before reuse.
- If your baby is teething heavily, consider having two or three teethers in daily rotation.
- Always wash your hands before handling clean teethers.
Choosing the Right Silicone Teethers and Accessories
When selecting teethers, opt for 100% food-grade silicone that is free from BPA, BPS, and phthalates. High-quality silicone is non-toxic, durable, and easy to clean. Bumkins offers a range of silicone teethers that are designed with safety and hygiene in mind.
For example, the Silicone Teething Charms: Green are a great option for attaching to pacifiers or other baby gear. They are made from food-grade silicone and are easy to clean and sterilize. These charms can be boiled or placed on the top rack of a dishwasher for convenient sterilization.

Another useful accessory is the Silicone Flat Reusable Bag 2 Pack, Lavender. While not a teether itself, this versatile bag can be used to store clean teethers and other small baby items, keeping them hygienic and organized. The silicone material is easy to wipe down and can be washed in the dishwasher, making it a practical addition to your baby care toolkit.

- Look for teethers with textured surfaces to provide extra relief for sore gums.
- Choose teethers that are easy to grip for little hands.
- Consider teethers that can be chilled in the refrigerator (not freezer) for added soothing effect.
