How early can babies teethe?

[SweetSunflowerBoo]

As title says really

How early can they teethe?

And how do I know if he's teething?

My little one has been dribbling a lot today with lots of bubbles which he never usually does and his front gums look a lot whiter

But I'm a FTM so I'm not sure

My first born son cut his first bottom tooth at 3 months!

@VanLife @Em45634 did you first know by actually seeing the tooth cut through?
The right side on the picture of my babies gums look whiter today and feel harder too

Yeh the tooth was there. I was a bit shocked. Usually bottom teeth are first.

It should be the first bottom 2 that come first they usually come in order

Mine is 4 months and has been really slavery for a bout 2 weeks but nothing yet

The bottom two come first. I have never noticed any signs in the actual gums themselves until the teeth come through but IME teething babies become very relentlessly whiny and if you put your finger in your mouth they don't suck it like they are trying to get milk or gently lick/explore it like they might have done previously, they really clamp down and rub from side to side, presumably to relieve the itching.

DS2 also used to get a bright red cheek when teething but my others didn't.

Babies can be born with teeth, so the teeth can come through at any age. But a lot of things people think are teething related are just developmental. Dribbling tends to start at about 8-12 weeks and is just when they start producing saliva which will later help them break down and digest food other than milk. They can't swallow on purpose at first which is why the drool comes out everywhere. Then by around 4-5 months the dribbling reduces a bit because they do get that swallowing reflex, which is another sign they are getting closer to getting ready for solid food.
