Dentinox Teething Gel
8/10 overall£5.00
A sugar-free gel with a mild local anaesthetic and antiseptic to numb sore gums on application.
The verdict
Dentinox Teething Gel, around £5, is a sugar-free gel with a mild local anaesthetic (lidocaine) and antiseptic, applied with a clean finger for fast, direct relief during severe flare-ups, suitable from 2 months. The NHS is clear it should be used sparingly and not as a first-line remedy, since effects wear off after roughly 20 minutes and it needs correct adult administration each time.
Where the other products in this category work through texture or cooling, Dentinox works chemically: a small amount rubbed onto the gum delivers a mild local anaesthetic (lidocaine) plus an antiseptic, giving faster, more direct relief than any teether can during a genuinely painful flare-up, particularly overnight when a baby won't settle with a toy alone.
The NHS is clear that teething gels should be used sparingly and only the sugar-free, licensed-for-age kind, applied with a clean finger and not overused, since numbing agents can mask other causes of distress if relied on too heavily. It's a targeted, occasional tool, not a first-line or all-day remedy — cooling teethers and gum massage should generally be tried first.
Compared with the physical teethers in this category, the gel's advantage is speed and directness for severe discomfort; its disadvantage is that it treats a symptom for a short window (typically 20 minutes or so) rather than giving a baby something to actively chew on, and it needs an adult to administer it correctly each time.
