Are Grillz Bad for Your Teeth? The Truth About Oral Health & Custom Grillz
It's one of the most common questions before buying a first set of grillz: are they actually bad for your teeth? The honest answer is "it depends" — mostly on fit, materials, and how they're worn. Here's what dental sources say, and how to wear grillz in a way that protects your teeth.
What Dental Research Actually Says
According to the American Dental Association, no studies have shown long-term hazards from wearing grills — but equally, there's no research confirming long-term wear is entirely risk-free either. In other words, grillz themselves aren't inherently dangerous, but how they're made and worn matters a great deal.
The Main Risks Dentists Highlight
Trapped bacteria and plaque. Grillz sit directly against your teeth, and food particles, plaque, and bacteria can become trapped underneath — increasing the risk of tooth decay, cavities, and gum disease if hygiene routines don't adapt.
Enamel and tooth damage from poor fit. Biting down on a grill that doesn't fit properly can put uneven pressure on certain teeth, which over time may lead to structural damage.
Material reactions. Grillz made from non-precious base metals can cause irritation or allergic reactions in some people, particularly with cheap, plated pieces.
Bad breath. Trapped debris and bacteria under a grill can contribute to persistent bad breath if the piece (and the teeth underneath) aren't cleaned regularly.
Why Fit Is the Single Biggest Factor
Almost every risk above is made significantly worse by a poor fit. A grill that doesn't follow the exact shape of your teeth creates gaps — and gaps are where bacteria, plaque, and food debris collect. A grill that presses unevenly puts extra force on individual teeth, which is where structural damage tends to start.
This is why custom, impression-based grillz are considered a safer choice than generic or DIY pieces — see our DIY vs custom grillz comparison for more detail. A precise, custom fit:
- Sits flush against your teeth with minimal gaps
- Distributes pressure evenly across the teeth it covers
- Reduces the surface area where bacteria can build up
How to Wear Grillz Without Damaging Your Teeth
Dental sources consistently recommend the same habits regardless of how well-made your grillz are:
Don't eat or drink with grillz in. This is the single biggest cause of trapped food and bacteria.
Don't sleep in your grillz. Overnight wear traps moisture and bacteria against your teeth for hours.
Clean your grillz daily with a soft brush and mild soap, and brush your own teeth thoroughly before and after wearing them.
Treat grillz as occasional jewellery, not all-day wear. Reserve them for events, nights out, or shoots rather than constant use.
See a dentist if you notice irritation. Sore gums, white patches, or persistent bad breath are signs to take a break and get checked.

What About Permanent Grillz?
It's worth distinguishing custom removable grillz from permanent (fixed) grillz, which involve a dentist filing down your natural teeth so a piece can be bonded permanently in place. This is irreversible and carries a different — generally higher — set of risks. For a full breakdown, see our permanent grillz guide. Removable, custom-fitted grillz don't involve any alteration to your natural teeth at all.
Frequently Asked Questions
Can grillz cause permanent damage to my teeth? Removable, well-fitted grillz worn occasionally with good oral hygiene are generally low-risk. Damage tends to come from poor-fitting pieces, prolonged daily wear, or eating/sleeping in them.
Are gold or silver grillz safer than cheap plated ones? Yes — solid precious metals are less likely to cause irritation or allergic reactions than plated base metals, and don't flake or wear away against your teeth.
Should I tell my dentist I wear grillz? It's a good idea, especially if you wear them regularly, so they can check for any early signs of irritation or decay during routine check-ups.
Do custom grillz remove the risk entirely? No precaution removes risk entirely, but a precise custom fit combined with good hygiene habits significantly reduces the main risks dentists highlight.
How often should I take a break from wearing grillz? Treating grillz as occasional jewellery — for events rather than daily wear — gives your teeth and gums regular breaks, which dental sources recommend.
