KEY MAINTENANCE TIPS

Essential tips to remember.

Never Use Hot Water

Hot water can permanently warp thermoplastic materials and ruin the custom fit. Always use cool or room-temperature water.

Avoid Harsh Chemicals

Bleach, alcohol-based mouthwash, and abrasive toothpaste can damage, discolor, or weaken the appliance material.

Keep Away from Pets

Dogs and cats are attracted to the scent and can chew or destroy an appliance within seconds. Always store in its case.

Store Dry and Ventilated

Moist environments promote bacterial growth. Always store the appliance dry in a clean, ventilated case.

WEEKLY MAINTENANCE

Weekly
deep cleaning.

In addition to daily cleaning, a weekly maintenance routine helps remove deeper stains, prevent bacterial buildup, and catch early signs of wear before they become problems.

01

Deep Cleaning

  • Soak the appliance using a manufacturer-approved cleaning tablet
  • Follow the manufacturer recommended soak time, typically 15-30 minutes
  • Rinse thoroughly with cool water after soaking
  • Deep cleaning helps remove stains and biofilm that daily brushing may miss
02

Stain Removal

  • Regular weekly deep cleaning prevents most staining
  • Avoid coffee, tea, or food contact with the appliance to minimize staining
  • Persistent stains may require professional cleaning at your provider office
  • Never use abrasive scrubbers or whitening products for stain removal
03

Bacteria Prevention

  • Daily brushing and weekly deep cleaning control bacterial growth
  • Always store the appliance dry and ventilated between uses
  • Replace your appliance case periodically or clean it weekly
  • A biofilm that cannot be removed may indicate the need for professional cleaning
04

Inspecting for Wear

  • Check for cracks, chips, or fractures in the acrylic material
  • Look for thinning or flattening of the tooth-contact surfaces
  • Examine hinges and adjustment screws for looseness or corrosion
  • Note any changes in fit, comfort, or retention compared to when it was new
05

Cleaning Storage Cases

  • Wash the storage case weekly with soap and cool water
  • Rinse thoroughly and allow to air dry completely
  • Inspect the case for cracks that could harbor bacteria
  • Replace the case if it becomes discolored or damaged
06

Checking Hinges and Adjustments

  • Ensure advancement mechanisms move freely without sticking
  • Check that adjustment screws are secure and not backing out
  • Look for any separation between the upper and lower trays
  • Contact your provider if any mechanism feels loose or difficult to operate

PROPER STORAGE

Storing your
appliance safely.

How and where you store your appliance when not in use significantly affects its lifespan and hygiene. Follow these guidelines for home, travel, and long-term storage situations.

01

Home Storage

  • Store the appliance in its designated ventilated case when not in use
  • Keep the case in a consistent, dry location away from direct sunlight
  • Ensure the appliance is completely dry before storing to prevent moisture
  • Place the case on a stable surface where it will not be knocked off
02

Traveling

  • Always carry the appliance in its protective case when traveling
  • Keep it in your carry-on bag, never in checked luggage when flying
  • Bring a travel-sized cleaning brush and mild soap
  • Consider bringing a backup case or cleaning supplies for longer trips
03

Humid Environments

  • High humidity can promote bacterial growth if the appliance is stored wet
  • Always dry the appliance before storing it in any environment
  • Use a ventilated case rather than an airtight container
  • In very humid climates, consider using a desiccant packet near (not touching) the case
04

Heat Exposure

  • Never leave the appliance in a hot car, near a radiator, or in direct sunlight
  • Heat can warp the thermoplastic material in minutes
  • A warped appliance will not fit and may require complete replacement
  • Keep the appliance away from any heat source including hot water
05

Pets

  • Dogs and cats are attracted to the scent of oral appliances
  • Pets can chew and destroy an appliance in seconds
  • Always store the appliance in its case and keep it out of pet reach
  • Never leave the appliance on a nightstand or counter unattended
06

Long-Term Storage

  • If you need to stop using the appliance temporarily, clean and dry it fully
  • Store in a ventilated case in a cool, dry place
  • Contact your provider before resuming use after a long break
  • Do not store for extended periods in plastic bags or airtight containers
07

Protective Cases

  • Use the case provided by your dentist or a dedicated appliance case
  • The case should be rigid enough to protect against crushing and have ventilation
  • Clean the case weekly and replace it if it becomes cracked or discolored
  • A well-maintained case extends the life of your appliance
APPLIANCE LIFESPAN

How long do
appliances last?

Understanding the typical lifespan of your appliance and the factors that affect it helps you plan for maintenance and eventual replacement. Your provider monitors condition at checkups and advises when replacement is appropriate.

01

Typical Lifespan

  • Most custom oral appliances last approximately 3 to 5 years with proper care
  • Lifespan depends on material type, frequency of use, and individual factors
  • Some appliances may last longer with excellent care; others may need earlier replacement
  • Your provider can assess remaining lifespan during routine checkups
02

Materials

  • Appliances are typically made from thermoplastic or acrylic materials
  • Dual-laminate designs combine a hard outer shell with a softer inner lining
  • Material choice affects durability, comfort, and lifespan
  • Softer inner linings may wear faster than rigid outer shells
03

Expected Replacement Intervals

  • Providers commonly assess replacement need at the 3 to 5 year mark
  • Replacement may be needed sooner if wear, damage, or fit changes occur
  • Weight changes, dental work, and bruxism can accelerate the need for replacement
  • Follow-up visits help your provider monitor and time replacement appropriately
04

Repair vs Replacement

  • Minor repairs (e.g., replacing a screw or band) may be possible in-office
  • Cracked acrylic or broken trays generally require full replacement
  • Repairing a severely worn appliance may compromise therapeutic effectiveness
  • Your provider will advise whether repair or replacement is appropriate
05

Factors Affecting Longevity

  • Daily cleaning and proper storage significantly extend appliance life
  • Bruxism (teeth grinding) accelerates wear on contact surfaces
  • Weight gain or loss can change fit and reduce effective lifespan
  • Exposure to heat, harsh chemicals, or pets can cause sudden damage
APPLIANCE LIFECYCLE

The replacement
timeline.

From delivery to replacement, your appliance goes through distinct lifecycle stages. Understanding this timeline helps you anticipate maintenance needs and know when to discuss replacement with your provider.

03

Routine Maintenance

Months 1 to 6

Daily cleaning and weekly deep cleaning become established habits. The appliance is monitored for fit and comfort.

04

Follow-up Visits

Months 6 to 12

Scheduled checkups assess appliance condition, fit, treatment effectiveness, and any side effects.

05

Long-Term Maintenance

Years 1 to 5

Ongoing care continues. Wear, fit changes, material degradation, and therapeutic benefit are monitored.

06

Replacement Window

Year 3 to 5 and beyond

Based on wear, material fatigue, and fit changes, replacement may be recommended by your provider.
