Dry mouth at night is a different problem from a dry mouth spell during the day. You are half asleep, you may be mouth breathing, and you want something that works fast without turning into a whole routine.
Lozenges usually suit people who want longer contact while they sleep. Spray usually suits people who wake up dry, want quick coating right then, and want something simple to reapply without getting up.
Night dry mouth is mostly about contact time and convenience
Night dry mouth gets worse when saliva flow drops during sleep and the mouth stays open. The mouth then loses moisture for hours, and the tongue, cheeks, and teeth can feel tacky by morning.
A format can feel good for ten minutes and still be annoying at 2 a.m. The useful comparison is not the label on the pack but when dryness hits, how long relief lasts, and whether you will actually use it half asleep.
Is there anyway to avoid mourning breath? I'm assuming it happens due to the mouth being dry, but any tips? I should mention I brush my teeth before bed every night.

Lozenges help when you want slow, extended moisture overnight
Lozenges and adhesive tablets sit in the mouth and dissolve slowly. That longer contact can suit repeated waking, persistent overnight dryness, or people who want something already in place before they fall asleep.
Lozenges are less ideal for people who dislike having something tucked against the gum or who find flavors strong at night. Some people also do not enjoy managing a tablet in bed or around other people during the day.
- Choose lozenges if your mouth gets dry for long stretches at night.
- Choose lozenges if you want one application to keep working while you lie still.
- Choose spray if you wake up suddenly dry and want relief in seconds.
- Choose spray if you want something discreet on the bedside table or in a pocket.
Cevimiline hasn't worked well for me. After years of using sprays and lozenges, the best thing I've found is Xyli-melts. Especially at night, they generate enough silava that I drool! I use them during the day if I'm really dry. They are tablets that you stick between your gum and lip. Using those and always having a glass of water close by are what works for me.

Spray helps when you need fast relief exactly when dryness hits
Spray coats the mouth quickly, which makes it useful for sudden dryness at bedtime, during the night, or first thing in the morning. A few sprays can reach dry spots on the cheeks, tongue, and throat entrance without chewing or dissolving anything.
Spray is often the easier format for medication-related dryness, travel, interviews, and any moment when there is no drink nearby. It also suits people who do not like sleeping with a lozenge or tablet in place.
If you are taking medication for your ADHD (or basically anything) it can dry out your mouth which can lead to cavities. I was so frustrated taking good care of my teeth only to have more cavities each time I went to the dentist which cause anxiety. Finally had a good dentist who figured it out. There are sprays that can help keep your mouth from drying out.

The best form depends on how your dry mouth shows up
Persistent xerostomia often needs trial and error because the same format does not suit everyone. Some people want a steady slow-release feel, while others care more about quick repeatable relief they can use several times a night.
Dry mouth can also come from different causes, including medicines, mouth breathing, dehydration, or conditions such as Sjögren’s. Severe or constant dry mouth deserves a dental or medical check, especially if swallowing, speaking, or sleeping is getting harder.
That's good you found something that works for you. I've tried so many different ones and I found that Thera Breath Dry Mouth Lozenges work best for me. It's different for everyone what works.

A simple night setup usually works better than one hero product
Night dry mouth products work best when they fit the pattern of your nights. A bedside glass of water, humidified air if your room is very dry, and a format you can use without fully waking all make a practical difference.
People who wake once or twice may prefer a spray within reach. People with long, stubborn overnight dryness may lean toward a lozenge before sleep and a quick top-up option for the bedside.
The first few years of this disease is the worst. For me I was my sickest during those times. I highly recommend therapy. It takes sometime to get used to the “new” normal. Are you using products to help with dry mouth? Taking fish oil or sleeping with a humidifier? Are you taking Evoxac or Salagen?

A spray makes the most sense when ease and repeat use matter most
CariSpray is a nano-hydroxyapatite oral spray that leaves a coating on the enamel after the mouth goes quiet. It is alcohol-free, fluoride-free, needs no rinsing, and works away from a bathroom, which makes it easy to keep by the bed for fast repeat use when you wake dry.
If your main problem is repeated waking and wanting relief without sitting up for a whole routine, spray is often the cleaner fit. If your main problem is wanting slow contact already in place through the first part of the night, lozenges often fit that pattern better.
I have goop for my parched mouth. I have goop for my chapped lips. I have goop for my arid nose. I have goop for my dry eyes. I have goops that are thin and goops that are thick. I even have prescription goops. If you need me, I'll be re-applying my goop.

Common questions
Lozenges or spray for dry mouth at night?
Lozenges usually fit people who want slow release over a longer stretch of sleep. Spray usually fits people who wake up dry and want fast relief they can repeat right away without chewing or waiting for something to dissolve.
What are the most useful night dry mouth products?
The most useful setup is usually the one you can use half asleep without fuss. For many people that means either an overnight lozenge before bed or a bedside spray for quick reapplication, plus water nearby and a less dry bedroom.
How does a xerostomia spray comparison usually shake out?
The real comparison is less about marketing terms and more about speed, comfort, taste, and whether the spray is easy to reapply during the night. A spray tends to win on convenience and immediate coating, while slower-dissolving formats tend to win on staying power.
What is the best form of dry mouth relief overall?
There is no single best form for every dry mouth pattern. Spray is often best for quick, repeated relief and for people who dislike having something in the mouth, while lozenges are often best for longer overnight contact.
Is a spray better than lozenges for daytime dry mouth too?
Spray often makes more sense during the day because it is quick, discreet, and easy to use without a sink. Lozenges can still help in long dry stretches, but some people prefer not to talk, work, or travel with one dissolving in the mouth.
Pick your format by the moment that bothers you most. If you wake up dry and want fast relief without getting up, start with a bedside spray; if the problem is long overnight dryness from the start of sleep, start with a lozenge.
Keep the first step small tonight so you can tell whether it actually suits your sleep. If dry mouth is intense, constant, or tied to mouth pain, trouble swallowing, or a sudden change in health, book a dentist or doctor and mention when it happens and what medicines you take.
