Which Oral-B model should I buy?

The differences between adjacent numbers are usually a feature or a box accessory rather than cleaning performance. A pressure sensor is worth having; travel cases and extra modes mostly inflate bundles.

Why is the same Oral-B a different price everywhere?

Retailers get their own bundle codes, so the exact package at one shop often does not exist at another. Compare the handle and the box contents as two separate things.

How much do replacement heads cost over time?

Recommended quarterly, and over a few years considerably more than the handle. Price a multipack for your chosen model before you choose it — that is the real cost of ownership.

The numbered range is a bundle ladder

Oral-B runs long numbered series where adjacent numbers differ by a feature or by what is in the box — an extra head, a travel case, a charging stand. Retailers also get their own bundle codes, so the exact product at one shop frequently does not exist at another.

Compare the handle, then compare the box contents. Merging those two comparisons is how people conclude one shop is cheap when it is simply selling less.

Heads are the real cost

Replacement heads are recommended quarterly and over a few years cost considerably more than the handle. Different head types carry different prices, and the handle you choose determines which heads you are buying for years.

This brand discounts very heavily and very often

Deep promotional discounting is normal here, which makes the "was" price a weak guide and the current cross-retailer spread a strong one. It also means the same handle can be near the top or the bottom of the range depending on the week.

Before you buy

Note the full model number and what is in the box.
Price a multipack of the compatible heads.
Work out handle plus a few years of heads and compare on that.
Check the sibling models — one number apart is often one accessory apart.
Compare across shops on the day, since discounting is frequent and unsynchronised.
