Packing for a trip might seem straightforward until you’re at airport security wondering whether your toothpaste counts as a liquid or how much mouthwash you can pack in your hand luggage.
Understanding airline luggage rules in advance can help you avoid delays, extra fees, and unnecessary stress.
This practical guide explains exactly what you can and can’t pack in your hand luggage and checked baggage, so you can travel with confidence.
Let’s break it down clearly.
Airports follow strict “liquids, aerosols, and gels” (LAGs) rules. This is where many oral care products fall.
Put simply: if your product isn’t completely solid, it will almost always be treated as a liquid.
That means yes, toothpaste is considered a liquid, along with many other everyday dental essentials.
This is the area that catches most travellers out. Many oral care items may not look like liquids, but they still fall under the same restrictions:
Toothpaste (all types, including whitening and sensitive formulas)
Oral gels (including oxygenating or gum-care gels)
Oral foams and dental mousses
Whitening gels or serums
Even thicker products (like gels or foams) are included because they can be squeezed or dispensed.
If you apply it from a tube, pump, or bottle, it’s almost certainly a liquid in the eyes of airport security.
One of the most common (and frustrating) issues at airport security involves liquids in your carry-on bag. Whether it’s toothpaste, mouthwash, or skincare, many everyday items fall under strict liquid restrictions and not following them can mean having your products confiscated.
Understanding the 100ml rule before you travel helps you pack smarter and move through security without delays.
When packing liquids in your hand luggage, you must follow three key requirements:
The 100ml rule is gradually being phased out at some airports across the UK and Europe, as new security scanners are introduced. These advanced systems are designed to allow passengers to keep liquids in their bags and potentially carry larger volumes.
However, it’s important to be realistic:
This means you should still pack as if the 100ml rule applies. It remains the safest way to avoid delays or having items confiscated, especially when travelling with essential toiletries like toothpaste, oral gels, or mouthwash.
