LIFE+ Earplugs for Dentists & Dental Hygienists

Foam earplugs are designed for construction sites, not surgeries. They block everything – including the sounds you need to hear. They’re one-size-fits-all, which means for most ear canals they either don’t seal properly (no real protection) or they’re crammed in too hard (uncomfortable after 20 minutes, let alone a full clinic day).

bollsen earplugs are made from medical-grade silicone, sized precisely to your individual ear canal via AR KI TECH, and designed to attenuate the high-frequency damage range of handpieces and scalers while preserving speech intelligibility. The difference in comfort over an 8-hour clinic day is significant. The difference in protection is measurable.

Yes – and this is the number one reason dentists avoid foam earplugs altogether. Standard foam plugs muffle everything: your patient says “that’s hurting” and you miss it. Your nurse calls out the next instrument and it sounds like she’s underwater.

bollsen earplugs work differently. Because they’re sized precisely to your ear canal using AR KI TECH, they seal cleanly without having to be crammed in. That means consistent, controlled attenuation – enough to block the high-frequency shriek of the air-turbine handpiece (peaks at 90–105 dB), while still letting speech frequencies through clearly. You can still hear your patient nod, speak, or signal discomfort. You can still hear your nurse.

That’s the difference between a plug that fits and one that doesn’t.

This is the most dangerous assumption in the profession. Here’s the honest answer: the damage is happening, you just can’t feel it yet.

Noise-induced hearing loss (NIHL) is cumulative and silent. Each burst of the air-turbine handpiece – typically 90 to 105 dB – causes microscopic damage to cochlear hair cells. Those cells don’t regenerate. The loss doesn’t show up on a routine audiogram until roughly 10 years of exposure, by which point a meaningful amount of high-frequency hearing is already gone.

The numbers from the research are stark:

• Dentists develop hearing loss at twice the rate of the general population
• 31% of dentists report tinnitus – and of those, 64% describe it as constant
• 96% of dentists currently wear no hearing protection at all

The fact that it doesn’t hurt doesn’t mean it’s not happening. By the time it does, the damage is permanent.

Yes. What you’re describing is called a temporary threshold shift (TTS) – your cochlea has been overloaded and is temporarily struggling to recover. It usually resolves within 16–48 hours. The key word there is temporarily. Do it repeatedly over years and it becomes permanent.

The asymmetry you’re noticing (left worse than right) is also very well documented. Studies show that right-handed dentists consistently show greater hearing loss in the left ear – because the high-speed handpiece is held in the right hand, positioned closest to the patient’s left side, and therefore nearest to your left ear. It’s not random.

If the ringing after a heavy day is something you’ve normalised as “just what happens” – that’s worth reassessing. It’s your cochlea telling you it’s under strain.

More than most dentists realise. Here’s what the research shows:

• High-speed air-turbine handpiece: 70–82 dB average, with peaks reaching 90–105 dB
• Ultrasonic scaler (Cavitron/piezo): 83–107 dB – often the highest exposure for dental hygienists
• High-volume suction (obstructed): up to 96 dB
• Multi-chair NHS surgeries: significantly higher cumulative exposure, especially with 6–10 chairs running simultaneously

Under the Control of Noise at Work Regulations 2005, the upper exposure action value is 85 dB(A). Above that, your employer is legally required to provide hearing protection and designate hearing protection zones. Most busy dental surgeries exceed this threshold regularly. Most practices don’t act on it.

As a practice owner or employer, yes – you have legal duties under the Control of Noise at Work Regulations 2005:

• 80 dB(A) – Lower Exposure Action Value: you must assess the risk and inform your team
• 85 dB(A) – Upper Exposure Action Value: you must provide hearing protection and hearing protection zones
• 87 dB(A) – Exposure Limit Value: workers must not be exposed beyond this level, even accounting for protection

A 2024 British Dental Journal analysis found that current GDC and BDA PPE guidance shows a “total absence of reference to noise levels and hearing impairment” – which means most dentists simply haven’t been told. That’s a gap in professional guidance, not a sign the risk doesn’t exist. The regulations still apply regardless.
