Illustration of the comparison; not a product photograph or scale drawing.
The Sonicare 5900 and 7300 share several everyday features, including a pressure alert, timed brushing guidance and a rechargeable handle. The 7300 adds more settings, an app connection, a visible pressure light and a charging travel case in the offer compared here.
Those additions are useful when they solve something you care about. If you expect to choose one setting and leave your phone outside the bathroom, the 5900 deserves a close look. If you want visual feedback and travel charging, compare the 7300 as a complete kit rather than judging the handle alone.

How we compared: This is a research-based comparison using Philips model information and the linked Amazon offers, checked October 23, 2026. We have not tested these toothbrushes side by side. We compare documented functions and kit contents, without treating manufacturer cleaning claims as proof that one handle will produce better results for every user.
Compare the exact model numbers
This guide covers black 5900 HX7131/02 and white 7300 HX7420/07. Philips sells several similarly named brushes, with retailer and market versions that may include different accessories. A search result that says “Sonicare 5000” or “Sonicare 7000” is not enough to establish which kit you are buying.
The linked 5900 offer describes two C3 heads and a charging stand. The 7300 offer describes three A3 heads, a charging travel case and a stand. Keep those bundle details separate from the features of the handle family. If you choose another color, multipack or seller option, recheck the model code and contents before carrying the comparison across.
Six settings or twelve: what the numbers mean
Philips lists two modes and three intensities for the 5900. The compared offer names Clean and Gum Health. That produces six combinations. The 7300 has four modes—Clean, Sensitive, Gum Health and White—with three intensities, giving twelve combinations.
This is a difference in choice, not twelve separate cleaning modes or a promise of twice the results. If you normally keep one preferred intensity, the extra combinations may make little difference. If you want a dedicated Sensitive setting alongside the other choices, the 7300 is the relevant option in this pair. Read what the settings change, then choose around the controls you will actually use.
Which pressure alert will you notice?
The 5900 uses haptic feedback to warn when it detects excessive pressure. The 7300 adds a visible light ring at the base. The useful question is whether you prefer to feel a warning or notice it while looking in the mirror.
We have not compared their sensitivity or responsiveness in use. A visible light does not, by itself, establish that the sensor measures pressure more accurately. It gives you another way to receive the signal. If pressure feedback is the main reason you are replacing your current brush, make sure you understand the indicator and its position before choosing. If you are brushing around a particular dental concern, use your dentist’s guidance on technique.
Decide whether the app earns a place in your routine
The 7300 offer advertises a connection to the Sonicare app for guided brushing and related content. That may appeal if you like prompts and want to spend time following your routine through a phone. The compared 5900 offer does not advertise that feature.
Before making the app the reason to upgrade, check current phone compatibility and decide where the phone would sit while you brush. Features that sound useful on a specification list can become unused extras at home. If you mainly want a handle that gives you timed reminders, both compared offers already describe a two-minute timer and 20-second BrushPacer prompts. Paying for an app makes more sense when you have a clear plan to use it.
Compare the included heads and future refills
The 5900 kit includes two C3 heads; the 7300 kit includes three A3 Premium All-in-One heads. These are different head styles, so comparing two against three without looking at the design misses part of the decision. An extra head is useful when it is a style you want to keep using.
Philips’ compatibility guidance identifies the standard click-on system used across these rechargeable families. Check the exact replacement pack’s fit and any supported smart features. You are not required to assume that every head with “Sonicare” in its name fits. Our Sonicare refill guide covers the important exceptions.
The travel case is the more practical upgrade for some buyers
The 7300 offer specifically lists a charging travel case. That can be useful if you want to charge while the handle is stored for a trip. It does not automatically mean the case has a built-in battery that will recharge the brush away from a power source. Check the case’s connection and instructions before relying on that.
The 5900 offer lists a USB-A charging stand, with no travel case included. Both compared offers say a power adapter is not included, and both advertise up to 21 days per charge. We have not verified those runtimes through testing. Compare the travel accessories you need, including a suitable power source, rather than assigning the 7300 a battery-life advantage that these specifications do not show.
Choose by the functions you will keep using
Choose the 5900 if its settings, pressure warning and included heads cover your routine. Consider the 7300 if you can name a clear use for its visual feedback, app connection or charging case. Add the current cost of suitable refills and any missing travel accessory to each kit before making the final comparison.
Check the selected model, seller, box contents and return terms at checkout. For a broader view of ongoing costs, see our electric toothbrush cost guide. The best value in this pair depends on the complete offer and the extras you expect to use, not the size of the number printed on the handle.

Common questions
Does the Sonicare 7300 have twelve cleaning modes?
No. The compared model has four modes and three intensities, producing twelve combinations. The 5900 has two modes and three intensities, producing six combinations.
Is the 7300 travel case a charging case?
The HX7420/07 offer compared here lists a charging travel case. Check its power connection and instructions; a charging case should not be assumed to contain a battery for charging away from a power source.
Does the 7300 last longer between charges?
Both linked offers advertise up to 21 days per charge. We have not measured their runtime, and those matching stated estimates do not support a battery-life advantage for either model.
Do I have to keep buying the same included head style?
Confirm alternative heads against Philips’ compatibility guidance and the exact refill package. These families use the standard click-on system, but physical fit and support for individual smart features are separate checks.
