Though we'd probably say that a large coffee is the most important part of our mornings, experts will tell you that it's actually brushing your teeth.
Sure, it's not as fun as tucking into a delicious breakfast (scrambled eggs on rye bread for us, please), or as satisfying as that first sip of coffee, but it doesn't have to be a negative experience either.
Especially where the Oral-B Pro 2 2500 CrossAction Electric Toothbrush is concerned.
Down from £79.99 to just £29.99 for the next 48-hours in Amazon's End of Summer Sale, this savvy toothbrush has racked up almost 50,000 reviews and is beloved by users, from people with sensitive gums to those with a strict whitening regime.
Why we rate it:
The toothbrush, which is approved by the Oral Health Foundation, features Oral-B's 3D technology, the brush head oscillates, rotates and pulsates to break down 100% more plaque than a usual manual toothbrush.
It also helps you time brushing for 2 minutes, with a timer that notifies you every 30 seconds that you need to change the area your are brushing.
Suffer from sensitivity? The brush has a gum pressure sensor, which reduces brushing speed and alerts if you brush too hard, to protect sensitive gums.
It also has two cleaning brushing modes: one for a daily clean and another for gum care so you can make sure every bit of your teeth is properly looked after.
The brush also comes with a travel case, which, as anyone who is an electric toothbrush convert will tell you, is very useful.
What the reviews say:
With almost 50,000 reviews on the shopping website, it's clear that this Oral-B toothbrush has the blessing of dentists and those dedicated to good oral care alike.
People love that the brush is "very manoeuvrable" compared to other electric toothbrushes, that it has two speeds and all the features feel thoughtful and useful rather than "gimmicky".
They are also impressed by how long a full charge lasts ("a week"), and feel it is the "perfect compromise" between an affordable price and an effective clean.
